A production supervisor was making his rounds one day when he gingerly stepped around a key conveyor belt. At the end of the belt, some water was being thrown off the belt surface and formed a puddle on the floor, causing a slip hazard. Not noticing the danger, the supervisor fell on his butt in front […]

A good check to determine if your oil injected rotary screw compressor is running efficiently is to do a timer test of the load/unload cycles. A rapidly cycling compressor — one that loads and unloads in a cycle that last less than a minute — is inefficient.  A best case compressor would be one that […]

A compressed air expert was asked to help with some calculations of a base case for a potential project.  The compressor supplier provided a free compressed air assessment where the inlet flow of the compressor was logged with an anemometer, rather than measuring the output of the compressor discharge. The data showed fairly low flow […]

A metal products manufacturer was using a water-based paint to provide a corrosion-proof coating on their products. The paint was previously solvent based, so the plant staff decided to install a compressed air mixer to prevent any risk of explosion. But air mixers were expensive, so the maintenance personnel simply installed a compressed air powered […]

A wire manufacturer used a refrigerated air dryer to condition the air from their three compressors. The dew point required in the plant was near 35° F, and the maintenance staff were confident of the proper operation of the dryer — because the onboard dew point reading on the dryer control panel said that the readings […]

There is a great entertainment value in watching the many movies or reading magazines about superheroes who possess amazing powers, and more than a few of us have wished we could be granted such skills — so we too could save humanity from evil. But this is not far from reality. In the world of […]

Many air compressor operators choose to use timer drains to remove liquid that is captured in separators, traps, receivers and filters in a system. Rather than using gravity feed or a float system, these drains open and expel the liquid, and an amount of compressed air, from the system after a set number of minutes. […]

Dust collectors using reverse pulse compressed air cleaning are often a problem in industrial plants. These dust collectors are usually located on the top of bins that collect dust and debris from industrial processes. A fan blows the contaminated air through a set of filters, in the form of bags or cartridges. The flow of […]
