GT Compressed Air Filter Specifications

GT SERIES Compressed Air Filters (12 - 1625 SCFM)
GT Series Filters employ an INTERNAL TIE-ROD to mount elements (EF Series Elements) in the filter. Maximum Operating Pressure: 290 psig (20.0 bar). 
Maximum Operating Pressure: 290 psig (20.0 bar). Maximum Operating Inlet Temperature: 176F (80C). Differential Pressure for Element Change: 10 PSI
GT Series Filters for Compressed Air

Alpha-Pure GT Series Compressed Air Filters are engineered to deliver filtered compressed air to meet specific requirements. With 4 primary efficiency options (P,X.Y,A), it is possible to meet the full range of ISO compressed air standards.

  • GT filters offer four (4) ranges of efficiencies, removing contaminants as small 0.01 micron at up to 290 psi (20barg)
  • Connection sizes range from 1/4" to 3" NPT pipe sizes.
  • A protected auto float drain (2mm orifice) is standard for optimal and reliable removal of liquid contaminants.
  • Body and Housing is zero-porosity aluminum with a durable epoxy powder-coat finish
  • Corrosion-resistant internal coating protects the filters and provides for a long service life.
  • Filter combinations are configured to meet specific application requirements.
  • Filters comply with PED and perform as per related ISO 8573 standards.
  • Filters with a -G suffix are equipped with differential pressure gauges for easy maintenance and energy efficiency. 

P: Pre-Filter / Particulate Filter (Filter/Element air flow direction is out side to inside)
X: General Purpose Filter/ Water Removal (Filter/Element air flow direction is inside to outside)
Y: Coalescing Filter/ Oil Removal (Filter/Element air flow direction is inside to outside)
A: Activated Carbon Filter/ Odor Removal (Filter/Element air flow direction is outside to inside)

NOTES:

  1. Activated Carbon Filters: Grade A must not operate in oil saturated conditions. Grade A elements should be replaced periodically to suit the applications but must be changed at least every six months. Grade A will not remove certain gases including carbon monoxide and carbon dioxide.
  2. Flow rates are based on a 100 psi (7 bar) operating pressure. For flows at other pressures use correction factor table. For maximum flow rate at a given pressure, multiply filter model flow rate by the correction factor corresponding to the working pressure.
  3. All filters are suitable for use with mineral and synthetic oils.
  4. Gauge type differential pressure indicators are fitted to models with -G suffix.
  5. All filters are in conformity with the Pressure Equipment Directive (97/23/EC)

Pressure Correction Factors

Flow rates are based on a 100 psi (7 bar) operating pressure. For flows at other pressures use correction factor table. For maximum flow rate at a given pressure, multiply filter model flow rate by the correction factor corresponding to the working pressure.
