Particularly useful where space is limited; horse-power required, as indicated below, is based upon pressure of about one pound per square inch, being increased proportionately for each additional pound of pressure oyer one pound; air tank is not absolutely necessary, but when steady, well-regulated blast of specified pressure is needed, it is preferable to direct blast into tank provided with relief valve, which can be regulated^to give desired pressure; size of air pipe to convey the air should be as large as the nipple or short pipe fitted in each blower; it is highly important that conducting pipes should not only be of suitable size, but as free from elbows and turns as possible, in order to minimize the power required to force the air through.
