Air Compressor Intake Safety Filter Element Kit (Outer Core 25150150-004P1 + Inner Core 25150150-004P2) – Dedicated Filtration Set for Industrial Screw Compressors
Brief Introduction
This filter assembly is purpose-built as an intake safety device for screw-type air compressors, comprising one outer filter element (004P1) and one inner filter element (004P2). When used together, they progressively remove suspended particulates, airborne dust, condensed moisture, and light oil mist from the ambient air before it enters the compression chamber. The performance of this assembly directly influences the service life of compressor bearings, rotors, lubricating oil, and downstream separation systems, making it an essential item in routine preventive maintenance schedules.

Key Feature Highlights
▎Integrated Two-Stage Filtration
The outer element P1 acts as the primary stage, intercepting coarse contaminants first. The inner element P2 then functions as the secondary stage, removing residual fine dust. This coordinated arrangement balances the workload between the two filters, preventing premature saturation of either unit while maximizing total dust-holding capacity.
▎Dependable Media Performance
Manufactured using specially treated composite paper, the filter media maintains structural stability under humid, high-temperature, or oil-mist conditions. It resists moisture-induced collapse, fiber shedding, and pressure-related deformation. Uniform pleating ensures adequate effective filtration area.
▎Low Resistance, Reduced Power Draw
The element geometry prioritizes smooth airflow passage. While maintaining specified filtration efficiency, intake resistance is kept to a minimum. This helps reduce compressor inlet vacuum pressure, preventing unnecessary power increases caused by restricted airflow – directly contributing to energy-efficient operation.
▎Precise Dimensional Accuracy for Quick Installation
All critical dimensions – including end-cap seal positions, center tube diameter, and overall height – are machined to standard drawings. These match the filter housings of most mainstream screw compressors. After removing the old elements, the new ones slide directly into place without adjustments to piping or mounting hardware. A single operator can complete the swap within minutes.
▎Replacement Interval Guidance
As a general rule, replacement is recommended every 2,000 operating hours. For sites with poor ambient air quality or elevated dust concentrations, shorten this interval to 1,500 hours or less. During each shutdown maintenance session, check the differential pressure indicator reading – using actual pressure drop data provides a more accurate basis for determining replacement timing.
Why Choose This Assembly?
Prevents hard particles from entering the rotor meshing zone, significantly reducing wear and the risk of rotor seizure;
Limits contaminant ingress into the oil circulation loop, slowing oil degradation and lowering oil-change frequency;
Maintains unobstructed intake airflow, indirectly reducing per-unit electrical consumption for compressed air generation;
Universal fitment covers replacement requirements for most major compressor brands in the market;
Delivers stable, reliable filtration at a competitive cost – no need to rely on premium-priced sources.
Typical Applications
Centralized compressed air stations in machining, automotive, and general manufacturing facilities
Compressor units operating in high-dust environments such as cement plants, ceramic works, and mining sites
Continuously running medium-to-large compressors in textile, chemical, and power generation sectors
Scheduled maintenance filter stock replacements
