OLT Plus Series

Tank Mounted - Oil Less Air Compressors

OLT Plus SeriesOLT Plus UL 1450 CertificationGeneral Air Products’ has improved our tank mounted oil less fire protection air compressor offering as well – now referred to as the OLT Plus series. Standard single phase units are UL 1450 listed for fire protection and integrally mounted on ASME air receivers. We have improved the durability, reduced noise and simplified installation with the inclusion of a 30” braided stainless steel flex hose and 4 vibration isolation pads.

Tank mounted oil less air compressors are recommended air the ideal air compressor type for dry pipe sprinkler system applications. We highly recommend a tank mounted compressor when an accelerator is required on the dry pipe sprinkler system. Our standard OLT Plus series units are single phase, pre-wired with pressure factory pre-set and adjustable up to 60 PSI. High pressure, 3 phase and 50 Hz OLT Plus units are also available.

The OLT Plus Series fire protection air compressors cover 30 minute fill up times on sprinkler systems up to 1225 gallons in size.

Note: As of 2012 we stopped manufacturing our OLT Series fire protection compressors (light blue in color). Those models have been replaced by the new OLT Plus units. You can still find technical information on the obsolete oil less tank mounted compressors in the “Additional Information” tab below and we continue to offer technical support for all of our units however any orders placed for the old model numbers are upgraded to the new OLT Plus Units described on this page. If you have any questions please contact us at 800-345-8207.

Note: Each individual system requires an air maintenance device (Model AMD-1) per NFPA 13. Multiple dry valves may be supplied from a single tank mounted air compressor when using our AMD-1 air maintenance devices.
