Quick Overview

STAINLESS STEEL MINIATURE FRL SERIES

Filter, Regulator

Max Operating Pressure: 300 PSIG (20 bar)
Port Size: 1/4 in NFPT & G Tap Threads

Numatics' 72 Series is a stainless steel miniature FRL series available in 1/4 in NFPT or G Tap threads. All models feature a 1.5 oz bowl capacity. Other features of the Numatics 72 Series include:

  • 316 stainless steel construction
  • FKM seals
  • 5 micron filter element
  • Three grades coalescing - one adsorbing
  • Meets NACE specifications
  • High flow in a compact size

Particulate Filter

Particulate air filters are designed to separate liquid, water, rust, pipe scale, and debris from air lines. They should be installed upstream of the regulator to prevent contamination from reaching other components.

Water is removed mechanically by the deflector which causes the air to move in a swirling motion. The condensed water droplets are then centrifugally impounded upon the ID of the bowl then fall down past the quiet zone baffle to the water sump. Dry air passes through the sintered element utilizing depth filtration and removes debris down to specified micron size.

  • 316 stainless steel body construction
  • All seals made of Fluorocarbon (FKM)
  • Meets NACE specifications
  • Internal plastic parts
  • Acetal and ABS
  • Element polyethylene

Coalescing Filter

The coalescing filter is utilized when either clean air is required or longer component life is desired. This type of filter removes water and oil aerosols. It works differently than the particulate filter; dirty air enters the element from the center and passes through a field of glass fibers which cause the aerosols to form into droplets which are heavier than the surrounding air. The droplets grow larger as they pass through the element and gravity causes the oil drops to drain to the sump of the bowl. To maximize the life of a coalescing filter it should always be used after a 5 micron particulate filter or with the optional pre-filter.

  • 316 stainless steel body construction
  • All seals made of Fluorocarbon (FKM)
  • Meets NACE specifications
  • Internal plastic parts
  • Acetal and ABS
  • Element - vacuum formed borosilicate glass fibers
  • Cartridge element design
  • Inner and outer support cores prevent element from crushing in either flow direction

Regulator

Regulators are used to reduce pressure to a required working pressure. Utilizing optimum pressure can save companies both component life and many dollars in compressed air costs.

Regulators consist of a diaphragm which floats between a main spring (top) and a valve (bottom). By turning the adjustment knob clockwise, the main spring is forced onto the rubber diaphragm which, in turn, is pressed onto the valve stem. When the spring pressure becomes greater than the air pressure in the control chamber below the diaphragm, the valve is forced down and flow begins. As flow continues, the pressure begins to build and air, via the aspirator tube, fills the control chamber and forces the diaphragm upward. As forces balance, the small spring under the valve piston causes the valve to close. The cycle continues in a balanced process of reducing or increasing flow based upon the downstream pressure.

Particulate Filter/Regulator 

The integral filter/regulator (‘piggyback’) is a two station component designed to filter and regulate compressed air when cost and space are of primary concern. As wet, dirty air enters, it immediately flows through the air deflector, causing the air to move in a swirling motion. After condensed water is centrifugally removed, air passes through the filter and into the regulator. The high pressure of the air is systematically reduced via the adjustment spring and valve and exits the housing as clean and dry air that is ready to work at the specified pressure.

  • 316 stainless steel body construction
  • All seals made of Fluorocarbon (FKM)
  • 0 - 125 PSI standard
  • Meets NACE specifications
  • Bonnet and knob - acetal
  • Internal plastic parts
  • Acetal and ABS
  • Element - polyethylene
  • Internal metal parts
  • Valve - stainless steel
  • Springs - stainless steel

Coalescing Filter/Regulator

The Numatics C Series coalescer/regulator is a two station point of use air preparation system designed to provide superior filtration and regulation in one compact housing. The C Series combines a multiple support cartridge style borosilicate glass element with a regulator to assure the maximum performance of downstream components. Available with four different element grade choices, the C Series coalescer/regulator can be outfitted to attack and remove the exact type of contamination that is critical to a specific application.
