Why would you switch?
The main difference between a screw and piston (reciprocating) compressor is the way they compress the air. Screw air compressors use two meshing helical screws, while piston air compressors use pistons driven by a crankshaft.
Another difference is the moving parts as the screw compressor has two moving parts which are not in contact while the piston compressor has a lot of moving parts. The screw compressors operate at a lower temperature and integrate a good cooling system.
Screw compressors can be reliable and durable. In fact, screws are engineered to run 100%, all day, every day!
Disadvantages of Piston Compressor
Loud
150 to 250 decibels.
Higher carbon imprint
High oil carryover at more than 35 parts per million.
Lower efficiency
High energy requirement on reciprocating technology. Prone to belt slippage.
Advantages of Screw Compressor
Silent
60 to 75 decibels only.
Lower carbon imprint
Lower oil carryover at less than 3 parts per million. Thus, better compressed air quality.
Higher efficiency
Low energy requirement with the new screw technology. No belts needed.
- > Any piston compressor, either used or brand new, of any brand and should be in running condition.
- > Trade-in value is applicable to purchase of brand new Atlas Copco screw air compressor only.
- > Piston compressor must fall between10 to 30 horsepower.
- > The piston compressor(s) to be replaced can be multiple units provided that it will have the same or lesser total motor size with the replacement screw compressor.
- > Approximate trade-in value is Php3,500 per HP (subject to final assessment of Atlas Copco engineer)
- > Payment term: COD
