Clogged Drains can be a Hassle!

Clogged Air Compressor Drains

Many compressed air users utilize filters to trap dirt and moisture, and nearly EVERY compressed air user has an air storage tank.  Both of these items are great for trapping and removing liquid water from the air stream – preventing rust and corrosion in pneumatic tools and process equipment.

Usually, collected water at the bottom of a tank or filter is released by an automatic drain valve.  These handy devices open on a timer or float mechanism and spout pressurized water from the bottom of the reservoir.   The bad news is most drain valves are equipped with a very small orifice for draining collected condensate – it’s usually only 1/
4-inch.  This means that even a small piece of dirt or pipe scale can clog the orifice and prevent the drain from functioning properly.

For this reason, it’s important to check your filter and tank drains periodically to ensure they’re up to snuff.  Even if your compressor service provider checks them during regular maintenance, make a point to check them between visits for proper operation.  Most electronic drains feature a test button, and almost all drains can be rebuilt fairly cheaply if their seals or diaphragms have been damaged by pipe scale.

Catching a clogged drain can prevent huge hassles by keeping slugs of liquid water from entering your plant’s air header.  If you need advice on how to check your various plants’ drains, feel free to call your local Quincy Compressor distributor.
