Setup Procedure - AIR SYSTEMS INTERNATIONAL ASI-1000 Manuel D'utilisation

Venturi style air blowers (air horns/movers) function by utilizing the Venturi principle in which a small volume
of high velocity air is forced through small openings (e.g. nozzle jets in the base of the blowers) in order to
produce large volumes of low velocity air (See: flow chart on page 3). A minimum ½" I.D. hose is recommended
from the air supply source to the side inlet connection on the blower base. The maximum inlet pressure for
these units is 140 psi (9.7 bar).
Strict precautions must be taken when using Venturi style air blowers during applications that require gas free-
ing, tank entry, tank collapse prevention, or tank cleaning where volatile and/or toxic vapors are present. For
informational purposes, please consult the American Petroleum Institute's (API) publications 2015 and 2016
prior to performing any of the aforementioned applications. These publications may be obtained from:

Venturi air blowers have no moving parts, making them ideal for
ventilating hazardous areas. To remove static electricity, a ground-
ing lug is attached to the base of all of our Venturi air blower mod-
els. When in use in a volatile atmosphere, connect a ground wire
to discharge any static electricity that may develop. The Venturi
bases are made of a high quality aluminum alloy. When aluminum
is scraped across rusty steel, it may create a smear which has po-
tential to cause an incendiary spark. Be sure to take precautions
not drag the base along steel tanks or other steel surfaces.
All performance ratings in this manual were measured on a unit
supplied with clean, filtered air, with nozzle jets of the proper
diameter and with no clogs in any manner. Precautionary steps
should be taken to prevent clogging of the nozzle jets. Periodic
steam cleaning is recommended. NOTE: Brass bolts and nuts s
hould be used when securing the base assembly to the blower if
used in hazardous environments. Refer to the API guidelines on
proper grounding procedures.
When the Venturi air blower is used to supply fresh air in a confined space, the air supply compressor must use
a Grade-D air filtration package with sufficient capacity (cfm). A carbon monoxide monitor with alarm should
be installed inline. Consult factory for details: 1-800-866-8100.
1. Install desired inlet fitting no less than ½" in diameter.
2. Attach grounding wire between the base of the unit and the tank.
3. Tightly secure the air blower in place prior to turning on the air supply. Be sure not to restrict the
internal diameter of the air blower base as severe output flow loss will result.
4. Attach compressed air source.
Note: Venturi style air blowers are NOT meant to be used with ducting on the inlet or outlet as severe flow loss
will occur.
