Paint and Coating Options
Silencers are shipped with the manufacturer’s standard blue primer coat. For a durable, long lasting finish, pdblowers can apply special coatings with additional cost and lead time. Our most common option includes a primer coat of Sherwin-Williams KEM KROMIK, a rust inhibiting, corrosion resistant phenolic alkyd resin primer, followed by a finish coat of Sherwin-Williams SHER-KEM® high gloss metal finishing enamel. Contact us to discuss special coatings.
Standard industrial silencers are generally not individually leak tested and occasionally very small pin-holes may appear in welds. Because of the small size of these pin-holes, their effect on typical pressure or vacuum conditions is insignificant. If 100 percent air tightness is essential for gas service or other special applications, with additional cost and lead time the manufacturer will perform a 7 PSIG leak test. Contact us if you need this service with your order.
