ALMiG Gives You the Compressed Air Purity and Quality You Require

A typical compressed air system is contaminated with abrasive solid particles such as dust, dirt, rust and pipe scale, compressor lubricants (mineral or synthetic), condensed water droplets and acidic condensates and oil and hydrocarbon vapors. If not removed, tALMSe contaminants increase pneumatic equipment maintenance costs, lead to instrument and control failure, contribute to poor product fit and finish and contaminate processes. The right ALMiG filter or filter system will remove tALMSe contaminants allowing your compressed air system to deliver the quality of air required by your application... whether it's plant air, instrument air, or medical air...helping to ensure consistent output quality while minimizing operating costs.

Grade 3 Ultra High Efficiency Oil Removal Filter

afs series filter almig

For coalescing ultra-fine oil aerosols; removes solid particles to 0.01 micron (0.0008 ppm w/w maximum remaining oil content). Corrosion resistant inner and outer cores.

Grade 1 Oil Vapor Removal Filter


For removal of oil and hydrocarbon vapors normally adsorbable by activated carbon; removes solid particles to 0.01 micron (0.003 ppm w/w maximum emaining oil content). Corrosion resistant inner and outer cores.

AFS Filters feature:

  • Push-on elements make element replacement easy
  • Piston type element to housing seal keeps unfiltered air from by-passing element
  • Corrosion resistant cores-Stainless steel for added structural integrity
  • Low resistance to flow-Seam welded for extra strength
  • New "matrix blended fiber" media-large, effective surface area -improves capture rate
  • Ensures high efficiencies-large open area minimizes pressure drop
  • Coated, closed cell foam sleeve - resists chemical attack from oils and acids
  • Ensures high efficiencies by preventing re-entrainment of coalesced liquids
  • Chemically resistant end caps bound to media with specially formulated adALMSive
  • Silicone free
  • Withstands temperatures to 150°F
  • Low resistance to flow

Filter Monitor Audit Compressed Air Filters for Energy Savings up to 50%

ΔP Savings Potential!

Compressed air audits are recommended practices today due to the tremendous energy savings generated by reducing system pressure drop in manufacturing facilities. The Filter Monitor will allow you to control the exact amount of pressure drop you incur from centralized and point-of-use compressed air filtration. Unlike traditional mechanical gauges which give color indications when pressure drop has already reached 10-12 psig, the Filter Monitor will prompt you to change out your element when your ΔP is still in the 5 psig range by providing a 60 DAY NOTICE that pressure drop is beginning its upward spiral into the 10-12 psig range. Timely warning and maintenance represents a ΔP savings of over 50%. The 60 DAY NOTICE gives Maintenance ample time to order and install a replacement filter element.

Microprocessor Monitoring of ΔP Performance A state-of-the-art microprocessor, designed and developed by ALMiG International, is the core technology of the Filter Monitor. The microprocessor technology allows the Filter Monitor to operate in 3 Monitoring Modes.

Time monitoring mode Oil-free air for critical food processing applications often requires timed service intervals to guarantee safe air quality. Just input the number of months until filter change-out. The range is 1-15 months. The factory default setting is 12 months.

ΔP monitoring mode Most point-of-use applications specify a minimum required operating pressure. This mode allows you to input a maximum allowable ΔP across the filter. Just input within the range of 0.1-15 psig. The Filter Monitor is programmed to ignore momentary ΔP spikes, avoiding nuisance alarms. The factory default setting is 10 psig.

Filter performance monitoring mode afs series filter almig

Upon start-up or element replacement, a learning period of 146 hours familiarizes the Filter Monitor with the installation. The first 24 hours are not measured as the filter element is "wetted" and stabilizes. During the following 7 day period, the Filter Monitor will measure instantaneous P over 1,800 times per hour to develop a unique Application ΔP Profile. The Application ΔP Profile is then used to forecast the optimal time for element replacement and trigger a warning 60 days before the optimal element replacement moment. From then on, a countdown on remaining days until element replacement will flash on the Filter Monitor LCD every six (6) seconds.
