Many workers need protection from toxic and otherwise hazardous materials exposure but don't need a
hood with "all the bells and whistles". And in order to satisfy the need for a low cost, yet needed
quality fume hood, we offer the "economy" products. They provide the same high protection to the
operator and because of their novel construction, they can even be positioned over a laboratory
sink or other apparatus. And most important of all: They are all ductless and portable and can
be moved from room to room or lab to lab, wherever they happened to be needed the most.
The Economy hoods give the worker a high level of safety and protection against exposure to
hazardous substances wherever routine work is being done. The units are known for their
"low noise" operation because they recirculate instead of exhausting expensive conditioned
and/or heated air into the outside atmosphere.
The Economy hoods are available in three different sizes, from 23" long (front working length) to 48".

The SPI "EH" family of ductless portable hoods give the worker safety where the routine handling of
hazardous and toxic chemicals is routinely done. All units operate at very low noise levels and
because they recirculate they do not exhaust expensive conditioned and/or heated air into the
outdoor atmosphere.
The "EH" family are all compact bench mounted units that can be safely used for small amounts of chemicals.
A face velocity of 100 FPM (ft/min) ensures containment of fumes and particulates for worker protection.
An alarm will alert the worker when the airflow falls to an unacceptable level. The units can be placed
on any bench top, and an optional polypropylene spillage tray can be provided when required. The rear
of the unit has lighting to illuminate the work surface.
All mechanisms in the head section are on the clean side of the filter, with the switches and electrical
components being isolated from any contamination.
The patented filter clamping mechanism allows for the filter to be easily installed and ensures an even
seal at the filter face at all times to prevent bypass leakage.
For the main filter, one can select from 14 different types of carbon, which include special media for
vapors of organics, solvents, acids, mercury and formaldehyde. HEPA filters for particulate filtration
are also available to suit the application at hand.
ESD compatible hoods:
All three member of the "EH" family of SPI Supplies Brand hoods can also be ordered in EDS compatible antistatic plastic.
We apologize for the high price for the ESD compatible version but the special ESD compatible plastic is just
outrageously expensive and we have no other alternatives.
Available products:
Now that you have selected the basic hood,
it is now necessary to select the proper filter.
