Compatible Muffler for Yamada Pumps

The Dayton 22A609 muffler is designed for Yamada America models 6PY54A and 6PY55. It installs directly onto the pump to reduce exhaust noise during operation. This accessory suits maintenance teams and operators who need quieter performance from their existing diaphragm pumps.

40 Micron Filtration and Flow

The unit incorporates a 40 micron filtration element that helps protect downstream components from fine particles. Exhaust air passes through the media with minimal restriction, maintaining pump efficiency. Normal use produces a noticeable reduction in sound levels without increasing back-pressure on the system.

One-Inch NPT Ports for Direct Mounting

Each muffler features 1 inch NPT inlet and outlet ports that thread straight onto the pump exhaust. The rugged housing resists vibration and corrosion in shop environments. No additional brackets or adapters are required, so installation takes only minutes with standard pipe tools.

Questions about this item

How do I install the 1 in NPT muffler on my Yamada pump without cross-threading the ports?

Start the threads by hand until the muffler seats evenly, then tighten with a wrench no more than one full turn past hand-tight to avoid damaging the 1 in NPT connection.

When should I replace the 40 micron muffler element on my Dayton 22A609?

Replace the element when exhaust flow drops noticeably or back-pressure rises, typically after the filter media loads with particulate and can no longer pass air at the required rate.

What is the first limitation I will hit running the Dayton 22A609 muffler continuously on a Yamada 6PY54A or 6PY55 pump?

The 40 micron filtration rating is the first limit; as the element loads, back-pressure increases and restricts pump output before any mechanical wear occurs.
