Fantech Heat Recovery Ventilator Model SH 704 - 56 CFM

Indoor air quality problems have soared since the late 1970's when construction technology succeeded in developing energy efficient "tight" houses. Pollutants inside houses, which once escaped through cracks around windows and doors, are now trapped inside creating an indoor environment that is often 2 to 5 times more polluted than outside. Pet dander, mold spores, dust mites, allergens, tobacco smoke and other pollutants add up to poor indoor air quality.

Fantech's line of IAQ Products can help you solve these problems through better ventilation. Choose from a complete line of Heat Recovery and Energy Recovery Ventilators to bring fresh outside air into the house while expelling stale polluted air.

Fantech SHR Series Heat Recovery Ventilators are high performance, low maintenance units designed to improve indoor air quality and provide balanced ventilation in residential applications. Units include many installer-friendly features - easy-slide core guides, external electrical box, easy-access doors, and much more.

This compact HRV with easy-mount wall bracket is pefect for a small home or condominium. It brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. HRVs use what is called a "sensible" heat recovery core. This special core transfers heat from the exhaust air stream to the incoming air stream. Fresh incoming air is tempered by the heat that is transferred from the outgoing air to save on energy costs. The SH704 is equipped with automatic defrost mechanisms so even if you lie in the coldest climates you can use your HRV all year long.

Sizing For Your Residential Needs
HRVs/ERVs are typically sized to ventilate the whole house at a minimum of .35 air changes per hour. To calculate minimum CFM requirements, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .35.

SPECIFICATIONS
CASE: 24 gauge galvanized steel. Baked powder coated paint, antique white. Cabinet fully insulated with 1" (25 mm) aluminum foil-face high density polystyrene foam to prevent condensation and meet the requirements of the UL 94HF.
MOTORS: Two (2) German-manufactured, factory-balanced ebmT motors with backward curved blades. Motors come
with permanently lubricated sealed ball bearings guarantee long life and maintenance-free operation. Seven (7) year
warranty. Steep fan curves requires no balancing of airflows.
CORE: Aluminum heat recovery core configured for efficient cross-flow ventilation. Core is 8.5 x 8.5 (216 x 216mm) with a 8 (203mm) depth. Cores are manufactured by Fantech to withstand extreme temperature variations.
FILTERS: Two (2) Washable Electrostatic Panel Type Air Filters, 8.5 (216mm) x 8 (203mm) x 0.125 (3mm).
CONTROLS: Unit is designed to operate continuously on a single speed.
DEFROST: The automatic defrost cycle consists of a fan shutdown. When the supply air stream temperature goes below 23F (-5C), the supply motor shuts down while the exhaust motor continues to ventilate. Ambient air is passed through the unit for a period of 3 or 5 minutes. (see chart below) The supply motor will then re-start and run at the preset speed. This fan shutdown defrost cycle continues until the supply air stream rises above 23F (-5C).

Temperature range --- Run/Defrost cycle
F (C) --- (minutes)
23 (-5) to 14 (-10) --- 40 / 3
14 (-10) to 5 (-15) --- 30 / 5
5 (-15) & lower --- 20 / 5
