120R-200S (Riser Mount) and 120R-200T (Tank Mount)
The 120R Series of dry and pre-action sprinkler system compressors offer two models: a convenient, time saving riser mount and a space saving vertical tank mounted design. This system utilizes Gast’s own oil-less rocking piston style 120R compressor, the most powerful rocking piston air compressor on the market. The 120R delivers industry leading flow performance, longer life, and better electrical efficiency compared to competitive models. Included with this system is a durable digital pressure switch to provide a wide system capacity all in one model. This switch is designed to meet NFPA-13 standards (for dry and pre-action fire sprinkler systems) for initial pump up time and is rated for 940 system gallons @ 40 PSI and 2259 system gallons @ 18 PSI, and has the ability to set cut in and cut out pressures with the touch of a button. Many thoughtful details throughout these designs.
Where is my 120R made?
The 120R is manufactured in Benton Harbor, Michigan USA.
I am an OEM looking to specify a custom 120R configuration for my needs. What customization options are available?
Gast offers custom solutions factory direct and through our authorized distribution network. Custom options available, but are not limited to: wiring and connectors, capacitor mounting and covers, port configurations, alternative mufflers and filters, pressure gauges and regulators, and bulk packaging. Please consult the factor (firstname.lastname@example.org) or find a local distributor to inquire further.
How do I keep my 120R running at the same performance it left the factory?
Following the Gast recommended service intervals will help keep your compressor running at peak performance. We recommend service using a Gast 120R Preventative Maintenance Kit (part number: K1027) every 2000 hours or every 2 years and the Gast 120R Service Kit (part number: K1028) at 6000 hours or 5 years, whichever comes first.
Where can I mount a capacitor?
Included with your 120R is a mounting clamp and terminal cover to mount the compressor onto the body of the compressor. A capacitor cover (part number: K1031) is sold separately. Alternatively, the capacitor can be remote mounted by the end user.
I'm trying to replace my old Jun-Air OF1202 compressor with the 120R. Do I need special hardware?
The 120R was designed to fit in the same space as the OF1202 series and includes mounting brackets with flexible holes so you can utilize your existing mounting points.
Can I mount and operate the 120R on its side?
Yes. The 120R was designed and tested to run on its side and will maintain factory performance. This will require a Gast 120R Side Mount Bracket Kit (part number: K1032), sold separately.
Is Sound Shield technology available?
Coming soon. Please consult the factory (technical.gast.@idexcorp.com) for sound reduction options.
