Bard
BAROMETRIC FRESH AIR DAMPER - BFAD | STANDARD |
The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service | |
door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the | |
air inlet openings and to be mixed with the conditioned air. The damper opens during blower operation and | |
closes when the blower is off. Adjustable blade stops allow different amounts of outside air to be introduced into | |
the building and can be easily locked closed if required. |
|
Barometric Fresh Air Damper | BLANK OFF PLATE - BOP | OPTIONAL |
A blank off plate is installed on the inside of the service door. It covers the air inlet openings, which restricts any |
outside air from entering the unit. The blank off plate should be utilized in applications where outside air is not required to be mixed with the conditioned air.
Motorized Fresh Air Damper
MOTORIZED FRESH AIR DAMPER - MFAD | OPTIONAL |
The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The two position damper can be fully open or closed. The damper blade is powered open by a 24VAC motor with spring return on power loss. The damper can be controlled by indoor blower operation or can be field connected to be managed based on building occupancy.

COMMERCIAL ROOM VENTILATOR - CRV | OPTIONAL |
The
The commercial room ventilator (CRV) is a simple and innovative approach to improving the indoor air quality by providing fresh air intake and exhaust capability through the CRV. The damper can be easily adjusted to control the amount of fresh air supplied into the building. The CRV can be controlled by indoor blower operation or field controlled based on room occupancy. Two versions available (except on 1.5 and

The ERV consists of a unique “rotary energy recovery cassette” that provides effective sensible and latent heat transfer capabilities during summer and winter conditions. Various control schemes are addressed including limiting ventilation during building occupancy only.
The ERV is designed to be internally mounted behind the service door in the W**A, W**H or W**L model wall- mount units. It can be
