Electric compressors and their characteristics

In the construction industry, many tools use compressed air as a necessary power source. On construction sites, pneumatic hammers, nail guns, drills, wrenches, spray guns and other pneumatic tools are actively used. The use of compressed air, which is supplied by an air compressor, is also based on the operation of grinding machines involved in repair and construction work.

In the construction industry, electric compressors are often used, which are convenient in cases where it is possible to connect machines to an existing power line. All electric compressors are divided into reciprocating and screw compressors. Piston units, which appeared several decades ago, continue to remain in demand today among builders. Manufacturers of these devices use the latest materials, which has improved the reliability of this technology.

Electric reciprocating compressors are capable of delivering very high pressures and guaranteeing strong compression ratios.These devices can be safely switched on and off frequently, they are very effective in cases where compressed air is needed from time to time. The piston device is not as afraid of dust as the screw compressor. But screw models have many other advantages.

The electric screw compressor is a simple and efficient design that uses a system of interconnected rotors. The efficiency of screw models is higher than that of piston counterparts.

Mobile models that are actively used on construction sites are most often made with a screw. Such a device is easily transported and installed in the place where it is needed; it is connected to the mains via a simple socket.

If we compare electric compressors with diesel units, the following factors speak in favor of the former. One cubic meter of air obtained from the operation of an electrical installation costs 2.5-2.7 times less than the same amount of air obtained from a diesel compressor. The electric unit has a longer service life. During its operation, there are no vibrations, much less noise is produced, there are no exhaust gases that have a harmful effect. Diesel vehicles require engine maintenance, resulting in additional costs.
