Generator Muffler

Mac Muffler 01-6200 – Industrial Generator Exhaust Silencer

The Mac 01-series mufflers are proven silencers used on industrial diesel generators to cut exhaust noise while preserving backpressure within engine specifications. The 01-6200 variant belongs to this center-body (“bulged”) line built from heavy-duty 16-gauge steel with straight-through flow for reliable attenuation on fixed-speed gensets.

Typical 01-series dimensions include overall lengths in the 12–18 in range with common inlet/outlet sizes from 1.5 in to 2.5 in; a 2.0 in inlet/outlet is most common for mid-frame diesel sets. The design integrates end-in/end-out connections for easy placement inside generator enclosures or external exhaust runs, and it accepts standard pipe adapters, flex, rain caps, and hangers used on generator panels and enclosures.

• Construction: 16-ga steel canister, welded seams; center-body sound chamber
• Connections: End-in / end-out; typical 2.0 in (01-series supports 1.5–2.5 in)
• Application: Industrial diesel generator exhaust; suitable for Aurora diesel sets
• Noise control: Straight-through silencing for steady-speed gensets

This part is commonly supplied on Aurora Generators diesel units and field-replacements where a compact, durable silencer is required. It is widely used across commercial and marine generator applications and trusted for long service life.
