This feature saves power, as less cur rent is consumed at low speeds. The new "PeerVent" motor improve ments are the final step in placing the unit system on a strictly unit basis. The motor- generator outfit is eliminated.

Features of the Improved "PeerVent" Unit The "PeerVent" Unit of today has many important improvements, including the new "PeerFin" radiator.

This damper, as well as the mixing damper, has improved bearings. The mixing damper can be equipped with any type of automatic tem perature control. New fan housings have been designed, fan assembly, sliding in and out of the unit like the drawer of a desk. With the filter in this position the air is cleaned before it reaches the fans, radiator, etc., and the dirt therefore does not reach these parts. The new "PeerVent" Unit can be equipped with a positive-action "PeerTherm" Control, which automatically prevents the intake of cold air at any time when the room temperature falls below 65 (or any other predetermined temperature within a range of 15). Several types of "PeerVent" Units have now been standardized, and one or another of them will meet practically any architectural requirement, including instal lations in existing; buildings. Six different types of control have also been standard ized, including automatic control through out, hand control throughout, and various combinations of hand and automatic regu lation. providing large discharge capacity at con siderably lower tip speeds. "PeerVent" Drawings The mixing damper, radiator, motor and fan assembly, base assembly and air filter are all easily removable without the use of tools. The air filter, which is not included as part of the standard unit-equipment, can be of any make preferred and can be installed after the unit has been erected, without any changes in the unit. The filter rests upon supports below the motor and The accompanying drawings show the standard "PeerVent" heating and. ventilating unit. The unit illustrated on this page is equipped for thermostatic control of the mixing damper for controlling the room temperature automatically; and with pneumatic control of the recirculation damper. Hand controls can be provided if preferred. Adaptations of this unit can be furnished. Units can be provided for installation at the ceiling, also concealed and semi-concealed types, and other arrangements for special architectural requirements.
