HIGH PRESSURE DUCT BOOSTER®
FANS
|
|
|
Versatile and durable Tjernlund M and P-Series
Fans feature high pressure air handling performance with low noise and
extremely low power usage.
M-Series fans (metal housing) are ideal for
long runs or air supply and exhaust applications requiring exacting performance.
Use P-Series fans (plastic housing) as ultimate bathroom/spa exhausters
to eliminate fogged mirrors and lingering odors, super quiet. They
also work great for exhausting high moisture areas such as sub-slab radon
gas mitigation and dryer vent boosting. |
