Noisy pipes, valves, and other air-related noises are often accepted as the signs of a functioning system. Excessive pump noise, cavitation, and cascading in terminal units are considered normal. But air in system water can cause corrosion, reduced efficiency, poorly heated or inadequately cooled rooms, accelerated component wear and on-going complaints. There is a device that will keep your system free of air permanently. Less maintenance, quiet operation, fewer costs!. Unlike conventional air eliminators or air scoops, the Spirovent completely eliminates 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system. Consisting of woven copper wire soldered to a copper tube, the patented Spirotube creates a low velocity area in the Spirovent that scrubs the bubbles from the water. The air bubbles rise and collect in the air chamber before they are vented from the system via an integral automatic valve. Air problems become a thing of the past.

• Maintenance free
• No venting required
• Vent head is designed to stay dry, dirt and leak resistant
• 1/2" male thread port for pressure testing or remote venting of unwanted gases
• Quiet operation
• Increased component life
• Reduced oxygen based corrosion and pump cavitation
• The automatic air vent is guaranteed not to leak and can only be closed by the installer for a pressure test
• The air chamber has been designed so that dirt cannot reach the valve
• Large capacity collection chamber reduces the need for frequent draining
• Drain valve for flushing out the dirt
• Brass vent head
• Non-ferrous float
• ViTon seal and o-ring
• Copper coalescing medium

ZD10X12TZ Honeywell Parallel Action Automatic Rectangular Blade Damper 10" x 12" 24 VAC Strong & Reliable 24 VAC Spring-Return Motor The ZD is a power close and spring open damper. It has a 24-volt motor used to control circulating air in HVAC systems and used when a normally-open damper is required. The ZD is typically used with the TrueZONE and other electronic zoning systems.

• Mechanical visual position indicator for damper status
• Solid construction using extruded aluminum frame and blades
• Parallel blade design for low leakage performance
• Simple, easy-to wire, two wire installation with a third wire option M4 for LED open only light
• Reliable, strong, 24 volt spring return motor
• Fail-safe, normally open operation
• Ordering instructions: order ZD (dimensions 1) x (dimensions 2), (motor is always mounted on dimensions 2 side) for example, ZD10x8 is a 10 x 8 Inch damper with the motor on the 8 Inch side, but a ZD8x10 is an 8 x 10 Inch damper that has the motor on the 10 Inch side
• Damper can be installed in any orientation (mounting side can be on either the bottom or the side of the duct)
• Motor or actuators mounting - side or top
• 30 sec power closed/10 sec spring return
• 90 deg angular rotation

The field RC is furnished as standard equipment on many leading brands of oil or coal-fired heating equipment. It is calibrated to allow for easy adjustment to the furnace or boiler manufacturer's specifications. Designed for settings from 0.02 - 0.08", this control is so sensitive that instrumentation should be used when adjusting the unit during installation.

For proper operation and efficient fuel consumption in oil, gas, and/or coal-fired heating appliances, draft must remain constant. When it is, combustion is more complete, fuels are utilized efficiently, and money is saved. Field Draft Controls maintain consistent draft by counteracting the negative forces caused by changes in temperature and barometric pressure, as well as the effects of wind.
