Coltri Compact Nitrogen Booster
With a maximum operating pressure of 5000 psi (345 bar), Coltri Compact Nitrogen Boosters compress and purify nitrogen gas. Available with a 5.5 or 7.5 hp electric motor that delivers 7-9.4 CFM (200-265 L/min).
A booster compressor receives gas under pressure and is therefore more efficient and pumps more gas per horsepower than a standard compressor. Charging rate is variable and is based upon intake pressure that can vary between 29-73 psi (2-8 bar).
A nitrogen booster is equipped with a service stage to recover nitrogen blowby from the crankcase. The booster units are vented at each start-up to remove the nitrogen amount which eventually has been contaminated during booster standby.
