What are OLT Plus Series Oil-Less Tank Mounted Air Compressors used for?
OLT Plus Series Oil-Less Tank Mounted Air Compressors are used to provide compressed air for compatible fire protection systems. They are commonly used with dry-pipe and pre-action fire sprinkler systems that require supervisory air pressure.
Are these oil-less tank-mounted air compressors?
Yes. The OLT Plus Series is an oilless tank-mounted air compressor line for fire protection applications. The oil-less design helps reduce maintenance associated with lubricated compressor systems.
What fire sprinkler systems are these compressors used with?
These compressors are typically used with dry-pipe and pre-action fire sprinkler systems. Confirm the specific compressor model against the system design, sprinkler system capacity, and project requirements before ordering.
Are 400-gallon tank-mounted air compressors available in this series?
Yes, 400-gallon tank-mounted air compressors are available in the OLT Plus Series, depending on the selected model. Confirm the exact SKU, capacity, voltage, phase, and pressure range before purchasing.
How do I choose the correct OLT Plus compressor size?
Select the compressor based on the sprinkler system capacity, required fill time, pressure requirements, voltage, phase, and applicable project specifications. If you are replacing an existing unit, compare the current compressor’s model number and performance requirements before ordering.
Do tank-mounted air compressors require an air maintenance device?
In many dry-pipe and pre-action sprinkler applications, a listed air-maintenance device is required when using a tank-mounted compressor. General Air Products notes that a listed air maintenance device must be installed with tank-mounted air compressors, so verify the required accessory for your system before installation.
Are these compressors available in single-phase and three-phase models?

Are these compressors UL-listed or FM-approved?
Do not assume every configuration has the same listing or approval. Manufacturer documentation indicates certain OL Plus / OLT Plus fire protection air compressors are UL listed, but listing details can vary by model and configuration. Confirm the exact SKU against the current manufacturer's cut sheet before publishing UL, FM, or other approval claims.
Can these compressors be used as replacement fire sprinkler air compressors?
Yes, they may be used as replacement compressors when the selected OLT Plus model matches the existing system requirements. Confirm the old compressor model, system capacity, voltage, phase, pressure range, and accessory requirements before replacing.
Where are tank-mounted fire protection air compressors typically installed?
