Compressed Air Drain Valves

Moisture and condensate will accumulate within a compressed air system. Increased moisture in compressed air can become burdensome for manufacturing processes that require clean, dry air. One of the biggest impediments of moisture in a compressed air stystem revolves around corrosion and rust. Moisture can strip lubricants from components as well as create rust that inhibits operation of pneumatic controls.

Our industry expertise has enabled us to develop high-quality compressed air drain valves. These drains work with our Extractor/Dryer air filters as a comprehensive solution for all your air filtration needs.

Weep Drain - Standard 

The La-Man WEEP DRAIN or petcock, model #10535, is the standard drain supplied on all our Extractor/Dryer models. This drain is designed to constantly weep a very small amount of air, .16 to .2 CFM at 100 PSI. The drain should always be open in order to allow the extracted moisture to depart the base of the Extractor/Dryer® unit. If noise or air loss is a concern, please see our patented automatic Float Drain, which is specifically designed for the Extractor/Dryer.

Cycle Drain 


The CYCLE DRAIN, model #520CD, is used with the Model #520A & 520B only. This drain will automatically expel liquids from the Extractor/Dryer. The cycle drain requires intermittent air flow for operation. There is no air loss.

Float Drain


Our patented automatic FLOAT DRAIN, model #500FD, was specifically designed to fit all models of the Extractor/Dryer. The external bowl is used to collect liquids and contaminants removed by the Extractor/Dryer. Operation is dependent on the liquid level inside the drain bowl and is dispensed by a float controlled device. The Automatic Float drain will drain under normal operating conditions without reducing or relieving the pressure to the Extractor/ Dryer. The automatic float drain prevents any air loss and noise. A clear drain hose is provided.

Electronic Drains


The La-Man® line of ELECTRONIC DRAINS can be added to any Extractor/Dryer, compressor or surge tank, and drip legs. Adjustable intervals and discharge times available in various models. These drains work especially well with applications that have excessive amounts of water, which require controlled monitoring and must be matched to the drainage requirements.
