For retrofit applications and new construction

Serviceability features: Breathe new life into existing air handlers with FANWALL retrofit. Each fan can pass through most single-width doors, and each cube can be knocked-down for tight installations. Reduce maintenance costs with no belts or sheaves to change or bearings to grease. Save space with FANWALL arrays that can be applied in both vertical and horizontal airflow arrangements and save up to 50% in space and cabinetry.

Noise-reduction features: The acoustical benefit of FANWALL arrays is the low-frequency sound reduction of its smaller more efficient fans. Each backward inclined airfoil fan is custom designed and manufactured to the job’s design criteria. The optimum use of smaller, more energy-efficient direct-drive fans improves energy efficiency. The patented Coplanar Silencer^® that attenuates sound within each cube often eliminates the need for sound attenuators and their associated static pressure penalty and costly concrete inertia pads.

IAQ equipment supported: Building owners who upgrade to a FANWALL array can increase airflow to applications where sufficient airflow was previously a challenge. An array can easily replace (within the same footprint) a single or dual fan system with an array of smaller more efficient fans. The FANWALL array produces a uniform piston of air that better utilizes the face area of filters and coils for increased life and capacity.

Thermostat compatibility: Building automation controls or motor control center.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: In many cases, access limitations are a barrier to a fan or air handler replacement because replacement cannot be accomplished without the time and expense of a major tear-out and reconstruction project. A FANWALL system can minimize this and other barriers. Individual cubes can be navigated into tight spaces to avoid major demolition and reconstruction and provide flexibility in staging projects with significant access barriers.

Warranty information: Twelve-month warranty from startup or 18 months from shipment. Extended warranties are also available.

Special installation requirements: The modular design allows individual cubes to be navigated through a standard 3-foot door and assembled inside the existing air handler cabinet. This eliminates the need and associated cost of having a crane on-site.
