Air compressors are devices that press air into a smaller space for use under high pressure. They’re used in inflating gadgets, spray painting, pressure washing, fountains, and more. This article will explain in detail the types and features of air compressors found in Kenya and their maintenance.
All to Know on Types of Air Compressors
A fact: The earliest air compressor was the lung. The first mechanical compressor was developed in 3000 BC for the melting of materials like gold that required high temperatures. Today, air compressors are widely used. They are an integral part of everyday activities.
Types of Air Compressors
Centrifugal Air Compressors
These air compressors are large and typically have 500 horsepower (HP). They are reliable since they have no wearing parts except bearings and seals. They compress air to plant pressure and deliver it to the dryer. They are mainly used in refineries and processing plants.
Rotary-screw Air Compressors
They use a rotary-type positive-displacement mechanism in a continuous sweeping motion hence very little pulsating or surging of flow. They are smaller than centrifugal ones and have a power range of 5 to 350 HP. They are used in window units, refrigerators, and more.
Reciprocating Air Compressors
These are types of positive displacement air compressors whereby air is sucked into a chamber and compressed using reciprocating pistons. Their power range from 1 to 30 HP and they are mostly found in sandblasters, air guns, spray paint machines, et cetera.
Scroll Air compressors
A scroll air compressor works in a circular motion using two interleaving scrolls to compress or pump air. Typically, their power range is 2-30 HP. They are widely used in refrigeration and offer one of the most affordable air compressor price in Kenya. Below is a scroll air compressor.
Axial Air Compressors
They are rotating, airfoil-based compressors in which the air flows parallel to the axis of rotation or axially. They are normally driven by an electric motor or a gas turbine. They are an important part of power stations, jet and ship engines. They have a power of 5 to 350 HP.
Diaphragm Air Compressors
A diaphragm air compressor uses a flexible membrane to compress air. For this reason, it is the best compressor for pumping toxic air and explosive gases. These compressors are also used in scuba diving and inflating. Their power generally ranges from 3 HP to 200 HP.
Maintenance of Air Compressors
Below are three tips to ensure your air compressor runs smoothly.
Changing Air Compressor Oil
Start by draining your compressor and turning it on for a moment to warm the system and thin the viscosity of the oil. Add new oil and replace the fill cap.
Removing and Installing the Air Filter
Do this by removing the screws that attach it to the compressor and gently removing it. Install the new filter and replace the screws.
It’s advisable to perform the procedures above regularly to maintain your air compressor. Clean it frequently and follow the instructions indicated in the user’s manual.
Air compressors are important in every pneumatic operation and machinery. Their usage has seen great progress in numerous fields; agriculture, manufacturing, construction, transport, and many more. They are affordable and most are environmentally friendly.
