Low-cost Utility Blower Available At Surplus
By George Potter

A few more notes on the surplus blower --

I've had several direct inquiries (and seen a couple on MMD) about
the blowers I mentioned a few days ago [190417 MMDigest].

1. The blowers have a pair of terminals that accept 1/8" push
terminals for power input.

2. While on the workbench (see photo), the noise at 120 VAC input
voltage is 77 decibels (dB), and the noise with blower operating
at 240 VAC is 94 dB.

3. Both noise measurements were made about 3' from the blower.

4. The 30" of static pressure that I noted in original post was with
zero flow; the pressure will drop (significantly) with any airflow.

5. Yes, the cooling fan is independent of air flow through the blower.

6. I was asked if this blower could be used to produce vacuum for
a player piano.  I don't know of a player piano's requirements, but
yes, one could attach a hose to the inlet to the blower and have vacuum
for whatever.  Inlet is the flat bottom of the "blower" and one would
need to glue or otherwise attach a fitting to take advantage of the
vacuum.

7.  At 120 VAC input (or even a bit higher), the "noise" should be
easily contained by a simple box to hold the blower (and a baffled
intake).  At 240 VAC input it will definitely take some effort to
tame the noise.

Regards,
George Potter
