  • 1 cfm air consumption at 87 psi balances power with compressed-air efficiency
  • 91 dBA sound level meets typical industrial noise requirements

Pneumatic Piston Vibrator 397 lbf

The Dayton 1DYR1 is a cast-iron piston vibrator that delivers 397 lbf at 87 psi with a continuous duty cycle. It suits plants that need reliable material flow in bins, hoppers or chutes where electric vibrators are impractical.

Upgrade from intermittent or lower-force units

A jump to this model is worth it when existing vibrators stall under load or cannot run continuously without overheating. The 3,500 vpm maximum speed and 7.1 cfm air flow sustain steady agitation for bins up to 3,970 lb capacity.

Check air supply and mounting before ordering

Verify the compressed-air system can maintain 87 psi at the required flow rate through a 1/4 in NPT inlet. Ensure the structure has a flat bolt-on surface for the 4.52 in by 2.75 in footprint and that 91 dBA sound levels meet local noise limits.

Questions about this item

What bolt pattern and clearance does the 4.52 in by 2.75 in base need for mounting?

The vibrator uses a bolt-on mount with an overall length of 4.52 in and overall width of 2.75 in; allow space for the 3.62 in height and 1/4 in NPT inlet and BSPP outlet connections when planning the mounting surface.

How do I connect the air supply to the 1/4 in NPT inlet without creating a leak at startup?

Apply thread sealant to the 1/4 in NPT inlet fitting, torque to the manufacturer's specification, then pressurise slowly to 87 psi while checking the BSPP outlet and housing for leaks before running at 3,500 vpm continuous duty.

When should I inspect the piston and seals given the 91 dBA continuous duty rating?

Schedule a visual and auditory check every 500 operating hours; listen for changes in the 91 dBA sound level and monitor the 7.1 cfm air flow at 87 psi, as increased consumption or noise indicates piston or seal wear.
