Source Screw Air Compressor Oil Filter for Manufacturing, Repair, and Maintenance

Strategic Sourcing Guide for Screw Air Compressor Oil Filters

Understanding Technical Specifications and Part Compatibility

When sourcing screw air compressor oil filters, the primary objective is ensuring exact compatibility with the specific compressor model and operating environment. The market presents a wide array of part numbers, ranging from specific manufacturer codes like 6.1961.0 and 1625165613 to generic model identifiers such as GTA-30 or H071102. Buyers must recognize that a filter labeled as a "Standard Component" may still vary significantly in internal construction depending on the original equipment manufacturer (OEM) requirements. For instance, the product data indicates specific dimensions such as 10080mm or larger industrial sizes like 420420*560mm, which are critical for physical fitment within the compressor housing.

The filtration media itself is a crucial technical variable. Available data points to the use of glassfiber as a primary material, with media ratings specified in ranges such as 1um-3um or 10-15um. These micron ratings define the filter's ability to capture particulate matter and contaminants from the lubricating oil. A filter with a 1um rating offers finer filtration than one rated at 10-15um, but the selection must align with the compressor's internal tolerances and the manufacturer's recommended maintenance schedule. Selecting a filter with an incorrect media rating can lead to either insufficient protection of the screw elements or excessive pressure drop, which reduces system efficiency.

Furthermore, the physical structure of the filter must match the installation type. The data highlights "Stationary Type" installations and "Closed Type" structures, which are typical for industrial screw compressors. The cylinder position is noted as "Horizontal," a configuration that influences how the filter is mounted and how gravity or pressure affects oil flow. Buyers should verify that the new filter's physical dimensions and mounting interface match the original part number exactly. Discrepancies in dimensions, such as confusing a 240240320mm unit with a 160160270mm unit, can result in installation failures or oil leaks. The condition of the product is universally listed as "New," but the internal integrity of the glassfiber media must be verified through supplier documentation rather than visual inspection alone.

Compliance, Certification, and Quality Standards

In the industrial procurement of oil filters, certification serves as a baseline indicator of a supplier's commitment to quality management systems. The observed product listings frequently reference ISO9001 and ISO9001:2015 certifications. These standards indicate that the manufacturing facility adheres to international quality management principles, ensuring consistent production processes. However, buyers should understand that a certification on a product listing does not guarantee that every individual batch of filters meets the same rigorous standards without third-party verification. The presence of these certifications suggests a supplier has established procedures for traceability and quality control, which is essential for maintaining the reliability of critical machinery components.

Beyond general quality management, specific performance standards are vital for oil filters. The product data mentions standards such as "10080mm" or "420420*560" which represent physical dimensions, but buyers must also look for compliance with filtration efficiency standards. While the provided text notes media ratings like 1um-3um, it does not explicitly confirm compliance with specific industry filtration standards (such as ISO 4406 for cleanliness codes) for every listed item. Therefore, procurement teams should request test reports or certification documents that verify the filter's ability to meet the required cleanliness levels for the specific screw compressor application.

The concept of "Standard Component" is also relevant here. While some filters are marketed as standard components, the variation in part numbers and dimensions suggests that "standard" in this context often refers to the availability of the part rather than a universal industry standard. Buyers must verify if the filter meets the specific OEM specifications for their compressor brand, such as Atlas Copco, rather than relying solely on the "Standard Component" label. Additionally, the observation of "Customized" and "Non-Customized" options indicates that suppliers may offer tailored solutions. If a buyer requires a non-standard dimension or a specific media rating not found in the generic catalog, they must confirm that the customization process maintains the integrity of the ISO9001 quality framework.

Cost Drivers and Pricing Variables

The pricing for screw air compressor oil filters exhibits significant variance, with observed ranges in the market spanning from 1 USD to 235.71 USD. This wide disparity is driven by several factors, including the complexity of the filtration media, the physical size of the unit, and the level of customization required. Smaller filters with basic glassfiber media and standard dimensions, such as those around 10080mm, tend to occupy the lower end of the price spectrum. Conversely, larger units designed for heavy-duty industrial applications, with dimensions like 420420*560mm, command higher prices due to the increased material cost and manufacturing complexity.

The degree of customization is another major cost driver. Products listed as "Customized" or those supporting "Logo Customized" services often carry a premium. While some suppliers offer "Neutral Packing" or "Box" packaging at standard rates, others may charge extra for specific "Carton" packaging or custom branding. Buyers must evaluate whether the cost of customization provides tangible value or if standard packaging is sufficient for their internal logistics. Furthermore, the "Delivery Method" and "Lead Time" influence the final landed cost. Express delivery options, which promise delivery times of 1-3 working days, typically incur higher shipping costs compared to standard freight methods.

Minimum Order Quantity (MOQ) also plays a role in the effective unit cost. The observed MOQ range spans from 1 PC to 60 units. For buyers with low maintenance needs, a supplier with an MOQ of 1 PC allows for flexible purchasing without tying up capital in inventory. However, for high-volume procurement, negotiating a lower unit price by ordering closer to the 60-unit threshold can significantly reduce the total cost of ownership. Buyers should analyze their annual consumption rates to determine the optimal order size that balances inventory holding costs with unit price discounts. It is crucial to note that the price range observed is a market observation and not a fixed standard; actual costs will depend on the specific supplier, the quantity ordered, and the current market conditions for raw materials like glassfiber.

Typical Applications and Industrial Use Cases

Screw air compressor oil filters are essential components for maintaining the operational efficiency of various industrial machinery. The data explicitly identifies "Manufacturing Plant Machinery Repair Shops" as a key application area. In these environments, filters are used to protect the screw elements of air compressors from wear and tear caused by contaminants in the oil. The "Twin-Screw Compressor" type is specifically mentioned, indicating that these filters are designed for the high-pressure, high-temperature environment typical of twin-screw systems. The "Air Cooling" and "Lubricated" attributes further confirm their use in systems where oil is used for both lubrication and cooling of the compression elements.

The versatility of these filters is evident in the variety of part numbers and dimensions available. Models like 1625165735 and 92735547 suggest compatibility with a wide range of compressor brands and models. The "Stationary Type" installation suggests these filters are primarily used in fixed industrial settings rather than portable or mobile units. The "Horizontal" cylinder position is a common configuration in large-scale industrial compressors found in factories, power plants, and processing facilities.

Buyers should also consider the warranty implications of their filter choice. A listed warranty of 1.5 years indicates a supplier's confidence in the product's durability. In industrial applications, filter failure can lead to catastrophic compressor damage, resulting in costly downtime. Therefore, selecting a filter with a robust warranty and a proven track record in similar industrial settings is prudent. The "New" condition of the products ensures that buyers receive fresh components with full filtration capacity, which is critical for extending the life of the compressor and maintaining oil quality.

Evaluating a supplier for screw air compressor oil filters requires a rigorous approach to verifying the claims made in product listings. The presence of "Customization" and "Logo Customized" support suggests that suppliers are capable of adapting to specific buyer needs, but buyers must verify the scope of these services. For instance, does "Logo Customized" apply to the packaging only, or does it extend to the filter housing itself? Similarly, the "Customized" attribute may refer to dimensional changes, and buyers should confirm that such modifications do not compromise the structural integrity of the filter.

The "Product Origin" is listed as China, which is a common manufacturing hub for industrial components. However, the origin alone does not guarantee quality. Buyers should request evidence of the supplier's adherence to the ISO9001 standards mentioned in the listings. This includes asking for valid certification documents and understanding the scope of the certification. Additionally, the "Delivery Method" of "Express" with a "Delivery Time" of 1-3 working days is a strong logistical indicator, but buyers should verify the reliability of this claim by checking the supplier's track record for on-time delivery.

The "Part Number" and "Model No" are critical verification points. Buyers must cross-reference the listed part numbers, such as 6.1961.0 or 1623051400, with their own equipment manuals to ensure compatibility. The presence of multiple models with similar dimensions but different part numbers suggests that even slight variations can exist. A thorough supplier evaluation should include a request for a compatibility matrix or a technical datasheet that confirms the filter's suitability for the specific compressor model.

Quality Control and Long-Term Procurement Considerations

Maintaining consistent quality in oil filter procurement is essential for the long-term health of industrial machinery. The "Condition: New" attribute is a basic requirement, but buyers must look beyond this to ensure the internal quality of the filter. The use of glassfiber media with specific ratings like 1um-3um or 10-15um requires strict quality control during manufacturing to ensure the media is free from defects and properly bonded. Buyers should inquire about the supplier's quality control processes, including in-process inspections and final testing protocols.

Long-term procurement strategies should focus on building a relationship with suppliers who can provide consistent quality and reliable delivery. The "Warranty: 1.5years" is a significant factor, as it provides a safety net against premature failure. However, buyers should also consider the total cost of ownership, which includes the frequency of filter changes and the potential cost of downtime if a filter fails. Selecting a supplier with a proven track record in the "Manufacturing Plant Machinery Repair Shops" sector can provide valuable insights into the filter's performance in real-world conditions.

The "Packing" options, ranging from "Box" to "Carton" to "Neutral Packing," also play a role in long-term logistics. Proper packaging ensures that the filters arrive in pristine condition, free from damage that could compromise the filtration media. Buyers should evaluate the supplier's packaging standards to ensure they meet the requirements for storage and transport. Additionally, the "Standard Component" status suggests that these filters are widely available, which can simplify the procurement process and reduce lead times for future orders.
