Pneumatic Products Breathing Air Purifiers - BAP Series

Breathing Air Purifiers (BAP) – BAP Series 

Pneumatic Products BAP desiccant dryer purifiers are designed to provide a continuous supply of clean, safe breathing air from your existing compressed air system. Every purifier is a complete full-capacity purification system that performs effectively with lubricated or non-lubricated compressors.

  • Meets OSHA and CSA breathing air standards.
  • Protects workers from ambient and compressed air respiratory hazards.
  • Increases worker comfort and productivity.
  • Simple installation – air and electric only.
  • RS-232 monitoring of system operations and maintenance schedule.
Pneumatic Products Single Tower Natural Gas Dryers - FSD-A Series

Single Tower Natural Gas Dryers – FSD-A Series

The FSD-A Series dryers are an economical alternative to twin tower drying systems in CNG vehicular fueling stations. Coalescing and particulate filters are included for, scale, liquid aerosol and desiccant fine removal, further enhancing drying performance and gas quality. Specifically engineered for NGV fleet refueling applications with low to medium flow.

  • Certified Quality Assurance – ASME Section VIII designed pressure vessels and piping designed per ASME B31.3
  • Dryer isolation during regeneration cycle – three-valve block and bypass piping
  • Optimized footprint provides ease of service
  • Superior Corrosion Resistance – stainless steel diffusers
  • Downflow Drying – eliminates fluidization to extend desiccant life
  • No Gas Lost to Purge – closed loop convection regeneration
  • Energy Savings & Complete Diagnostics – microprocessor based
  • Safe, Reliable & Dependable Operation
  • Electrical Enclosures for Class 1, Division 2, Group C and D classifications (Optional Class 1, Division 1) 
  • Heater Element and Over-Temperature Shutdowns 
  • Blower and Heater Interlocks
  • Air-cooled heat exchanger with TEFC fan motor, non-sparking fan blades, fan cycling control
  • Heavy-Duty blower ensures reliable operation
  • Incoloy sheathed, low watt density heater and insulated heater housing, dual set point temperature controller for monitoring and over-temperature protection
  • Moisture separator and condensate collection vessel
Pneumatic Products Single Tower Natural Gas Dryers - FSD-M Series

Series Series Single Tower Natural Gas Dryers – FSD-M Series

FSD-M Series dryers are an economical alternative to a drying system with an on-board regeneration package. These dryers are suggested for use on CNG vehicular fueling stations which see intermittent or low gas flow rates. Coalescing and particulate filters are included for particulate, scale, liquid aerosol and desiccant fine removal, further enhancing drying performance and gas quality.

  • On-Site desiccant regenerated with mobile regeneration system (MRS-15)
  • Certified Quality Assurance – ASME Section VIII designed pressure vessels and piping, designed per ASME B31.3
  • Dryer Isolation During Regeneration – three-valve block and bypass piping
  • Ease of Service & Superior Corrosion Resistance – stainless steel diffusers
  • Downflow Drying – eliminates fluidization to extend desiccant life
Pneumatic Products The Mobile Regeneration System - MRS Series

Mobile Regeneration System (MRS) – MRS Series

The Mobile Regeneration System (MRS15) is used to regenerate the FSD-M Series tower once the drying capacity has been exhausted.

  • Adsorbent media can be regenerated numerous times (5 year minimum life with proper maintenance)
  • Minimizes disposal of potentially hazardous solid waste
  • Guarantees restoration of throughput capacity and dew point performance capability
  • Closed loop convection heating of desiccant via nitrogen gas circulation
  • Removal of desorbed moisture via an air cooled condenser, separator and trap
  • Closed loop convection cooling of desiccant to eliminate risk of heat and dew point bumps during initial phase of drying
  • Weatherproof enclosure
  • Easily mounts in a standard pick-up truck bed
Pneumatic Products Twin Tower Natural Gas Dryers - FSD-T Series

 Twin Tower Natural Gas Dryers – FSD-T Series

FSD-T Series twin tower purification systems are completely self-contained, fully automatic, heat-reactivated, closed-loop blower purge desiccant dryers designed to remove water vapor from natural gas.

Using molecular sieve as the drying media, these systems will continuously dry CNG down to an outlet moisture content of 0.5 lbs/MMscf, or lower.

Specifically engineered for large flow heavy-duty NGV fleet refueling applications, FSD-T Series Twin Tower systems provide dry CNG 24 hours a day.

  • Certified Quality Assurance – ASME Section VIII designed pressure vessels and piping designed per ASME B31.3
  • Three-valve block and bypass piping for dryer isolation
  • Ease of Service & Superior Corrosion Resistance – Removable stainless steel diffusers
  • Downflow Drying – eliminates fluidization to extend desiccant life
  • No Gas Lost to Purge – closed loop convection regeneration
  • Energy Savings & Complete Diagnostics – microprocessor based
  • Safe, Reliable & Dependable Operation – 
    – Electrical Enclosures for Class 1, Division 2, Group C and D classifications (Optional Class 1, Division 1) 
    – Heater Element and Over-Temperature Shutdowns 
    – Blower and Heater Interlocks
  • Air-cooled heat exchanger with TEFC fan motor, non-sparking fan blades, fan cycling control
  • Complete Purification System – Factory mounted and piped coalescing 0.0014 ppmw oil & aerosol removal prefilter and 0.9m absolute particulate removal after  filter
  • Moisture separator and condensate collection vessel
  • Heavy-Duty blower ensures reliable operation
  • Incoloy sheathed, low watt density heater and insulated heater housing, dual set point temperature controller for monitoring and over-temperature protection
