While most competitors require numerous additional parts to assemble FRL components, the Numatics FlexiBlok® FRL products are easily assembled with 2 button head screws and an O-ring seal. This modular type design reduces the potential for leakage during assembly and lowers the overall cost since brackets or extra tools are not required.

The FlexiBlok® line is designed to be simple and economical with the following features:

• Service can be performed while the component is installed in the air line
• 22, 32, and 42 Series bowls feature a unique locking tab bowl - just pull the locking tab down, turn the bowl 45º, and pull down to remove
• The unique design of the 22, 32, and 42 series bowls allows the O-ring to be held captive on the bowl, making it easy to check and replace if necessary
• Differential pressure indicators are standard on all 22, 32, and 42 Series coalescers
• Particulate filters feature a standard 5 micron element (optional 40 micron element)
• Coalescing filters feature dual support cores which prevent rupture and collapse
• CircleVision™ bowls allow the machine operator or manager a clear visual indication of the liquid level in a filter or lubricator bowl from up to 40 feet away
• Every product is tested and approved for quality assurance

Manifold Regulator

The 14 Series Manifold Regulator allows several regulators to be chained together while maintaining a constant primary pressure to each regulator. This regulator features a dual spring design which covers any possible outlet setting without the need to indicate a specific spring, eliminating confusing options and part numbers. The regulator uses the inner spring for more precise, lower pressures, and the outer spring for middle to high pressures. As the smaller, inner spring is compressed, the larger, outer spring takes over for higher pressures.

Regulators consist of a piston which floats between the main springs (top) and a valve stem (bottom). By turning the adjustment knob clockwise, the main spring is forced onto the piston which, in turn, is pressed onto the valve stem. When the spring force becomes greater than the force of the air pressure in the control chamber below the piston, 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. When the underside piston force is greater than the main spring force, the piston is forced upward, causing the main valve to close. The cycle continues in a balanced process of reducing or increasing flow based upon the downstream pressure.

• High flow in compact size
• Locking adjustment knob
• Single pressure range suits any application
• Relieving or non-relieving models
• Can be installed as modular or individual unit
• Standard output pressure 0 - 125 PSIG

Miniature Manifold Regulator

The MR02 Series Miniature Manifold Regulator offers the flexibility necessary for many of today's applications. The MR02 Series allows several regulators to be chained together while maintaining a constant primary pressure to each regulator.

A system equipped with the Miniature Manifold Regulator can help reduce operation costs by reducing unnecessary downstream pressures and improve efficiencies by keeping them in one convenient location for easy adjustment.

• Can be installed as an individual or manifold unit
• Standard output pressure 0 - 125 PSIG
• 3 available outlet/gauge ports (one in front, one in back, and one in the bottom)
• Integral mounting holes allow for easy panel mounting
• Connects easily without adapters or independent manifold system
• Standard 5 mm tamper resistant adjustment
• Relieving or non-relieving models

Pilot Operated Regulator

• Three convenient sizes
• High flow in compact size
• Can be installed as modular or individual unit
• Standard output pressure 0 - 125 PSIG
• Relieving or non-relieving models

Particulate Filter/Regulator

• Four convenient sizes
• 5 micron element standard (40 micron optional)
• Can be installed as individual or modular unit
• Locking non-rising adjustment knob
• Optional CircleVision™ sight bowl
• Optional metal bowl (sight glass available on 22, 32, and 42 Series)
• Standard output pressure 0 - 125 PSIG
• Bowl seal held captive (22, 32, and 42 Series)

Coalescing Filter/Regulator

• Four convenient sizes
• Cartridge element design
• Inner/outer support cores prevent element from crushing in either flow direction

• Can be mounted as individual or modular unit
• Button head fill optional on all sizes
• Atomizing chamber develops longer life aerosols

Solenoid Soft-Start/Quick Exhaust Valve

• Three convenient sizes
• Lockout feature prevents unauthorized pressurization of system
• High exhaust capacity for quick depletion of pressure
• High inlet to outlet flow capability
• Connects easily to FlexiBlok ® Modular system
• Incorporated metering valve controls how quickly downstream pressure is reached, which controls the slow start feature

Solenoid Quick Exhaust Valve

• Four convenient sizes
• Lockout feature (located in slide valve) prevents unauthorized pressurization of system (22, 32, and 42 Series)
• Standard manual override (optional without manual override)

• High inlet to outlet flow capability
• Connects easily to FlexiBlok ® Modular system

Shut-Off Valve

The FlexiBlok ® Shut-Off Valve is an easy and inexpensive way to add shut off capability to an FRL. The valve includes a lockout feature designed for a padlock to prevent unauthorized downstream pressurization during maintenance. The shut off valve is usually mounted first in the assembly.

• Relieves downstream pressure when closed
• Lockout feature prevents unauthorized pressurization of system

Diverter Block

Designed to give FlexiBlok ® components total versatility, the diverter block mounts directly in line with the FRL combination. Additional components can then be manifold mounted in a compact manner that doesn’t cause excessive pressure drop. There are two available tapped ports per unit.
