EnviroMax Enclosure Blowers
A complete line of belt and direct drive exhaust blowers that are chemical resistant & available in standard and explosion-proof models. HEMCO blowers are designed to operate effectively and efficiently to remove noxious & hazardous fumes. Standard 115V 60Hz international electrical configuration of 220V 50Hz AC available.
Blower Recommendations
1. Blowers should be mounted on the roof in-order that the ducting leading to the blower inlet is under negative static pressure. If exhaust blowers are mounted inside the building, all ducting connected to the blower outlet will be under positive static pressure, if a leak were to develop in the section of the duct inside the building, toxic & or hazardous fumes could be forced out of the ductwork and into that area of the building.
2. To achieve the lowest practical noise level in the exhaust system, we suggest that the following measurements be used when there is no conflict with other specifications of the system:
Use vibration isolators or mounting blower exhaust assembly.
Install a blower fan that will deliver the correct CFM and static pressure with the lowest practical impeller wheel RPM.
If possible, use a duct size large enough to keep duct velocity under 1800 FPM velocity.
Use a flexible connection at the fan inlet to isolate mechanical transmission of noise from the ducting between the hood and the exhaust blower.
Exhaust blower system should be designed with the fewest possible elbows or other fittings. Use radius type elbows & avoid using square elbows. Use gradual tapered transitions where necessary, & avoid abrupt changes in configuration or cross sectional area.
3. When ordering an exhaust blower, specify the orientation of discharge desired. Vertical up blast discharge is the most common and will be supplied unless otherwise specified.
4. All fans are shipped with clockwise rotation when viewed from the motor end of the assembly.
5. For normal usage, the standard for both the blower housing and impeller wheel is epoxy coated.
6. Blowers used for hood exhaust at altitudes above 1,000 feet, may require a correction factor to provide the correct CFM and static pressure.
Contact factory for details relating to your specific application.

Fume Hood Exhaust Blowers Ordering Info
HEMCO offers a complete line of chemical resistant non-metallic exhaust blowers in belt drive or direct drive options in standard or explosion proof models. Ideal for applications where corrosion resistance is critical. These blowers are available in polypropylene or fiberglass construction.
Blower Recommendations
1. It is recommended that exhaust blowers be located at the end of the ducting which is typically roof mounted. This ensures a negative pressure through out the ventilation system. However for applications where the duct is going directly out through a wall above a fume hood,one option is to have a fiberglass direct drive blower installed in the top of the fume hood. By having the blower internally mounted, the installation is simplified and convenient for duct connection and servicing. However there would be an airflow sound element associated to having the blower hood mounted.
2. By keeping the exhaust duct as short and as straight as possible, the total resistance will be reduced and by keeping the diameter of the duct correctly sized to the flow volume, noise and static pressure can be reduced.
3. Blower wheels for polypropylene and fiberglass blowers are polypropylene.
4. Vibration isolators are recommended when mounting the blower assemblies
5. HEMCO recommends that a sash stop be installed on the fume hood to limit the sash height for operation. By having stop at a half open position, the total CFM can be reduced by 50%; thus by reducing the volume, energy loss, duct diameter, motor and blower size, and sound is reduced.
Blower Description
