When the Three Filters “Stray”: Air Compressors Plagued by Trips, Airend Seizure & High Energy Consumption

The core consumables for air compressor system maintenance consist of three filters: air filter, oil filter and oil-air separator element.

Regular maintenance and replacement are essential to ensure efficient and stable compressor operation.

Nowadays, counterfeit, generic and high-imitation alternatives for the three filters flood the market. Besides questionable supply channels, untrained personnel can hardly distinguish fakes from genuine products by appearance,

yet these counterfeits bring huge profit margins. It is commonplace that customers abandon genuine three filters and opt for counterfeit alternatives.

In this dilemma between genuine and counterfeit three filters, can counterfeits beat OEM parts by offering comparable quality at lower prices? As shown in TV drama logic,

the original genuine parts always possess unique strengths in performance and reliability.

Air Filter
The air filter removes dust and particulate contaminants from intake air. The cleaner the incoming air, the better protected the service life and performance of the oil filter, oil-air separator, lubricating oil and airend.
Manufactured with state-of-the-art technology and safest materials:
CompAir air filters enable smooth airflow while maximizing the prevention of dust particle ingress.
Genuine CompAir air filters adopt nano-coated membrane technology with filtration efficiency up to 99.99%;
The service life of nano-coated air filters doubles that of conventional filter media;
Surface filtration design enables self-cleaning of filter elements;
Advanced pleating positioning technology boosts dirt holding capacity by 50%;
Flame-retardant filter media with UR certification.
Oil Filter
The oil filter traps solid particles and impurities in compressor lubricant, keeping the oil circulation system clean and securing safe operation of the air compressor.
Features of high reliability, optimal efficiency and performance:
Imported filter paper thoroughly removes contaminants in lubricant; manufactured under strict quality assurance standards for long service life.

CompAir oil filters are assembled with dedicated filter components to deliver high performance and withstand high operating pressure. Adopting unique and sophisticated manufacturing processes,

genuine CompAir oil filters maintain outstanding reliability even under harsh operating conditions.

Oil-Air Separator Element
The oil-air separator separates lubricating oil from compressed air to guarantee compressed air quality.
Cutting-edge media technology reduces pressure drop and residual oil content while supporting environmental protection:

Genuine CompAir oil-air separators feature low residual oil carryover and low differential pressure. This translates to superior air quality and minimized operating costs

by lowering oil consumption and extending the service life of downstream fine filters installed inside the compressor.

Latest AOS media reduces flow resistance by 30%;
Residual oil content cut by 60%;
Service life up to 8,000 hours;
Eco-friendly filter materials adopted.
Consequences of Switching to Counterfeit Three Filters: Three Major Headaches for Air Compressor Operators

The filtration efficiency of the air filter directly affects the actual compression ratio of the compressor unit. Restricted by cost, counterfeit air filters use inferior materials and crude production processes,

leading to increased filter resistance, higher energy consumption and insufficient air delivery. If the filter element ruptures, foreign matter enters the airend, which may result in rotor seizure or permanent scrapping of the unit.

The filtration efficiency of the oil filter determines oil return volume and thus airend lubrication. Counterfeit oil filters are prone to clogging and rupture.

Clogging restricts oil return, triggering excessive discharge temperature and shortening the service life of lubricant and oil separator elements.

Insufficient oil supply also leads to inadequate airend lubrication and drastically reduces the airend’s service life. Once ruptured, unfiltered oil carrying massive metal particles flows into the airend and causes permanent damage.

The separation efficiency of the oil-air separator element governs oil consumption and residual oil content in compressed air. Low-quality separator elements easily clog or tear. Clogging leads to excessive motor current,

which may cause airend seizure in mild cases or contact burnout and severe accidents in serious scenarios. Ruptured separator elements cause heavy oil carryover. Massive oil accumulates in air receivers and pipelines,

triggering airend seizure and unexpected trips, as well as damaging downstream air treatment equipment and end-user machinery.

Rising power consumption, frequent airend seizure and repeated shutdown trips! Switching to cheap counterfeit filters seems easy, yet operating conditions become uncontrollable.

Air compressor users are confronted with these three persistent troubles. Stick with genuine OEM filters for guaranteed safety and stable quality!
