What size FRL unit do I need?

Match the FRL port size to your main airline size. For small systems with 1-2 cylinders, 1/4" is sufficient. For medium systems, use 3/8" or 1/2". For large systems with multiple cylinders or high flow requirements, use 1".

FRL Units — Filter, Regulator, Lubricator

SPAC FRL (Filter-Regulator-Lubricator) units are essential air preparation components that must be installed upstream of any pneumatic system. The filter removes moisture, dust, and oil contaminants from compressed air. The regulator maintains a constant downstream pressure regardless of supply pressure fluctuations. The lubricator adds a controlled mist of oil to the air for lubricating cylinders and valves. Available individually or as combined FRL assemblies in 1/4 inch, 3/8 inch, 1/2 inch, and 1 inch port sizes.

Why Buy From Shri Narayan Machinery LLP?

FRL units are not optional — they're mandatory for any pneumatic system to function properly. Running cylinders on unfiltered, unregulated air leads to premature seal failure, corrosion, and inconsistent performance. SPAC FRL units are cost-effective and compatible with all pneumatic brands.

Frequently Asked Questions — FRL Units

Yes. Compressed air from a compressor contains moisture, dust, and oil. Without filtration, these contaminants damage cylinder seals and valve seats, leading to air leaks and component failure. The regulator ensures consistent pressure, and the lubricator extends component life. An FRL unit is the most cost-effective investment in any pneumatic system.
