GAST offers custom solutions factory direct and through our authorized distribution network. Custom options available, but are not limited to: wiring & connectors, capacitor mounting & covers, port configurations, alternative mufflers and filters, pressure gauges & regulators, and bulk packaging. Please consult the factory (technical.gast@idexcorp.com) or find a local distributor to inquire further.

There are a few answers. Sound Shield is offered as an aftermarket upgrade to be installed yourself or at an authorized GAST distributor. Over time, GAST plans to introduce new 86R and 87R models with Sound Shield installed at the factory so please consult your local GAST distributor for availability. However, customers looking to buy GAST 86R or 86R models in bulk can consult the factory to consider creating a unique SKU with Sound Shield installed.

If properly fitted and operated under normal conditions of use, the remainder of the factory warranty will continue with Sound Shield installed.

Following the GAST recommended service intervals will help keep your compressor running at peak performance. We recommend service using a GAST Service Kit, as shown above in BUY KITS & ACCESSORIES every 2000 hours or every 2 years, whichever comes first. Additionally, if fitted with Sound Shield, the AS321 Silencers should be replaced during the same interval period.

Each compressor or pump configuration yields slightly different results, however, GAST testing has shown either a reduction in exhaust temperature or negligible temperature changes. Please consult the factory for specific model temperature data.

There is no impact to the life of the unit when proper preventative maintenance is performed. We recommend replacing our Sound Shield AS321 Silencers every 2000 hours or 2 years, whichever comes first.

Each compressor or pump configuration yields slightly different results, however, GAST testing has shown that vacuum models see negligible changes while pressure models see minimal changes in flow. Please consult the factory for specific model flow data.

No, the internal silencer located within Sound Shield takes up the entire port; therefore, additional mufflers or filters cannot be added.
