Application:
These silencers are recommended where minimum silencing is required and ambient noise levels are medium to high.

Construction:
Aluminized Steel: Nelson Silencers through 26” O.D. are fabricated of aluminized steel as standard materials. This material has a maximum operating temperature of 1250°F.

Mild Steel/Aluminized Steel: Nelson Silencers 30” O.D. and larger are fabricated of mild steel and aluminized steel. All silencers 30” O.D. through 36” O.D. have aluminized steel bodies with all other components fabricated from mild steel. Silencers 42” O.D. and larger are fabricated from mild steel.

Silicone Aluminum Paint: Nelson Silencers through 26” O.D. are given a coat of high heat resistant silicone aluminum paint.

Primer/Silicone Aluminum Paint: Nelson Silencers 30” O.D. and larger are given a coat of high heat, rust inhibiting primer and then a top coat of high heat resistant silicone aluminum paint. Physical properties are maintained up to 900°F* on aluminized steel and 1100°F* on mild steel.
