EnviroMax BioEnclosures BTT
EnviroMax Filtered BioEnclosures are engineered and built to protect a process from surrounding contamination and personnel from hazardous elements. They are engineered to meet your equipment size and design requirement. Instrumentation and samples are safely protected by a laminar downward flow of HEPA filtered air and the user is protected by the face velocity of entering air.

EnviroMax BioEnclosure Specifications
EnviroMax
Superstructure is constructed of square tube steel with electrostatic applied epoxy powder coat finish. Rear wall is of composite resin and the side walls are of tempered glass. The front features a hinge-up safety viewing window for loading and set-up of equipment and a clear access opening below for user operation. The worksurface is fabricated of type 304 stainless steel which includes a full width perforated front area for air to exit the enclosure and an exhaust plenum below the surface with duct connection for 100% exhaust. HEPA filtration is ceiling mounted providing ISO 5 clean air into the enclosure. HEPA filters are 99.99% efficient and include a pre-filter. Enclosure is equipped with fluorescent lighting, light switch, fan switch with speed control, magnehelic gauge, and support table.
HEPA filtered clean air is introduced into the enclosure creating a laminar downward airflow pattern that exits through a perforation across the front of the worksurface. This bathes the instrumentation, samples and process in class 100 (ISO 5) clean air and ensures that it is protected from outside contamination.
Air also enters through the sash opening on the front of the enclosure. This air has a face velocity of 100 fpm which upon passing the frontal plane of the sash opening is immediately drawn down and exits through the perforation across the front of the worksurface. This inward flow of air serves as the protection for the user and by exiting through the perforation, contamination never breaches the air curtain created by the laminar downward airflow from the filter modules.
C.C.S. Floor Mounted Enclosures BTT

Features HEPA filtered air supplies and HEPA filtered exhaust air, to ensure a clean work zone free of contamination, protects work & environment. A safe change filter housing can be incorporated into the system if required.

Mobile Containment Control Systems 72” wide X 96” deep X 108” high, HEPA supply & HEPA exhaust air

Containment Control Systems provide enclosures for safe dispensing of powders to meet COSSH and GPM requirements. The C.C.S. can be designed to eliminate potential hazardous vapors or particulate where recirculation is not an option...

• The C.C.S. is designed for the elimination of potentially hazardous vapors or particulate in a non-recirculating exhaust system.

• Standard sizes are 6’ X 4’, 6’ X 6’, 8’ X 4’,and 8’ X6’. Sizes can be customized to meet your laboratory needs.

 

• Fluorescent lighting, fans, gages, controls and electrical are provided.

 

• Floor mounted containment booths are available in either unitized (pre-assembled) or modular (assembled on site) construction.

• On the front of the unit is a clear vinyl strip curtain that allows easy access to move
pallets or drums in and out. An air-gap underneath the vinyl strip
curtain ensures an inward flow of air, that sweeps across the floor.

• Extraction fans are automatically controlled to ensure near constant air flow in-order to compensate for filter loading.

EnviroMax Enclosure Blowers
AA 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 Recomendations

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 and 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:

a. Use vibration isolators or mounting blower exhaust assembly.

b. 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.

c. Use a flexible connection at the fan inlet to isolate mechanical
transmission of noise from the ducting between the hood and
the exhaust blower.

d. 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 Recomendations

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.
