Description of the SBD Motor Actuator: The Smart Bypass Motor Actuator is a Digital differential pressure controller with an integrated PI loop and intelligent software. The Smart Bypass Damper is the only industry bypass solution that can automatically measure, monitor and maintain the designed operating static pressure of the HVAC system in all modes of operation. The Smart Bypass Damper includes all of the accessories needed for field installation. No measuring instruments are required.

HONEYWELL SPRD10 Zonefirst SPRD Static Pressure Bypass Regulating Damper 10",

SPRD10

Honeywell SPRD Static Pressure Regulating Damper, 12", Round, Import

• Single-blade, steel barometric damper used to bypass excess air when majority of zone dampers are closed
• Counter-balanced weighted arm to control bypass air for zoned systems
• Air pressure in duct system increases as zone dampers close, pushing the SPRD open automatically
• Arm and weight both adjustable to control amount of air bypassed
• Recommended for low pressure systems with less than 0.5" WC
• For larger systems and tighter pressure control, use Mard damper and static pressure controller (SPC)
• Additional weights available

Arzel STKSB-E8x16 EzySlide Rectangular Duct Damper 8 x 16"
The rectangular EzySlide dampers have the mounting plate and actuator mounted on either the side or bottom of the damper. If the mounting plate and actuator is on the longer dimension the damper is referred to as a bottom-mount damper. If the mounting plate and actuator is on the shorter dimension the damper is referred to as a side-mount damper

The URD series of round motorized dampers are a double layered blade design with an integrated poron sealing gasket. The superior design insures long life and zero maintenance. URD dampers are easy to install, easy to wire up and come with a 5 year warranty. The URD damper is constructed of heavy 24 ga galvanized steel with factory rolled stiffening beads. The nylon bearings and ThermoTuff drive shafts insure smooth, quiet operation and provide a thermal barrier to the motor. The URD is designed to operate reliably at static pressures up to 1.5 in-WC. The UL listed MA-ND5 actuator is a 24 VAC three wire power open/power close type-rated at 18 in-Lbs. of torque. It includes an integrated wiring terminal block and a NEMA 1 rated housing. The MA-ND5 motor features bright green and red LED's which correspond to the open and closed position of the blade. The motor also includes adjustable end stops for Min/Max blade position, that allows for field balancing of the full or minimum cfm flow, into a particular zone or area. The position LED's will illuminate regardless of the end stop positions.
