General Features: The 3GR Series is available in 9 sizes from 100 to 600 CFM (45 to 285 l/s), rated for working pressure up to 16 bar, and delivers a pressure dew point as low as +3degC. An electronic no-loss drain with strainer removes condensate without wasting compressed air, while a micro controller with pressure dew point display gives precise monitoring. Low pressure drop, typically below 0.2 bar, keeps energy consumption down, and the range is tested and certified to IS 11989 / ISO 7183 / ISO 8673.

We are losing compressed air through our drain valve on every cycle -- is there a no-loss option?
Yes -- it has an electronic no-loss drain with a strainer, so condensate is removed without venting compressed air.
We need a specific size within a narrow CFM band rather than oversizing -- is there flexibility?
It is available in 9 sizes from 100-600 CFM, up to 16 bar, so you can match capacity closely.
Do you have third-party certification behind the performance claims?
Yes, it is certified to IS 11989, ISO 7183 and ISO 8673.
