Blower Nozzle

[Bob Bassett]

When did they replace the nozzle that blasted real air pressure with the wimpy ones on the market that are limited by the government to 30psi? Where can you get the old ones?

Bob,

You can still get them at Lowe's or Home Depot or Sears.

Just look for the the ones without the hole in the barrel.

I think that the low pressure ones are only mandated for shops that have to conform to OSHA standards.

You can tape over the holes and remove the orifice and drill it out if you get that energetic.

Technically, OSHA only requires that the outlet pressure not exceed 30psi if the nozzle is dead-ended, plugged, blocked etc. Most of the safety blowguns that I've seen have 2 decent sized relief holes in the side of the brass nozzle. These holes allow air to escape out of the sides and prevent pressure build up in the event that the end of the nozzle becomes blocked.

There are also types that have a relief valve to accomplish the same thing, but most that I've seen are only affected when the nozzle is blocked and operate pretty much like their older counterparts under normal circumstances.

full pressure air guns are still available.
the holes in the sides of good safety air guns boost the air flow substancially and usually reduce the need for air supplied from the compressor.

look for an air gun made by milton, camel, or cejn.

So the holes in the sides are good?

Thank you, I'm getting a degree in blow guns thanks to you fine folks.
