Back draft damper is made for insertion into inch ventilation ducts. The backflow damper RKI opens and closes automatically. It has a strong spring and can be installed either horizontally or vertically. The flap is suitable for retrofitting, since it is completely inside the duct.
Damper has 2 valves, designed for use in air conditioners (AC), dryers, exhaust, extractor or range hoods, heating ducts, vents and other HVAC applications.
INSTALLATION: The backflow flap is installed by inserting it into the ventilation pipe until it stops. The position of the spring should be horizontal for horizontal installations so that it can open and close optimally. The Backdraft shutter is installed so that the damper blades open only in the outflowing air direction..
The backflow flap opens and closes automatically at low air volumes. It has a smooth-running spring and an internal foam strip to keep the blades from rattling and can be installed horizontally or vertically.
Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ....
Broan 8" Universal Automatic Make-Up Air Damper with Pressure Sensor Kit
8″ Universal Automatic Make-Up Air Damper with Pressure Sensor Kit.
Interlocked make-up air damper systems meet IRC Code requirements for make-up air with range hoods over 400 CFM.
Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment.
Fresh air wall caps are required for use with Make-Up Air Dampers.
Interlocked make-up air dampers provide outside air when required to keep the air in the home fresher by allowing the range hood to operate at optimum levels.
Balance indoor air pressure by providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper.
Instead a sensor is attached to the exhaust duct to detect if the range hood is operating.
Slave dampers (MD6S, MD8S or MD10S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation..

Aquatec 6800 Booster Pump Kit for up to 100 GPD home RO reverse osmosis water filter system Standard or Manifold, includes pump, pressure switch PSW-240, transformer, 6840-2J03-B224 B221 Made In USA
This pump kit includes Aquatec pump 6840-2J03-B224 with heavy duty steel base plate with damper, PSW-240 pressure switch, transformer 110V USA plug, 1/4″ inlet/outlet for pump and pressure switch, detail instruction.
This pump is designed to increase the water supply pressure to a RO water system. Increase input pressure from 30-40 psi to 60-80 psi depending on the capacity of your RO system. This pump is good for under 100 GPD (gallons per day) RO systems Most home drinking RO systems are under 100 GPD.
Automatic ON/OFF operation. The pressure switch would sense the pressure in the output line, so when the output line is shut off or the storage tank is full or reaches 40-50 psi, the pump would shut off, and then when you start using water and tank pressure drops, then the pump turns back ON to replenish the tank..
This kit DOES NOT come with the optional (ESO) Electric-Shut-Off solenoid valve, so it would reply on your existing mechanical auto-shut-off valve in your RO system to turn off the water supply when the tank is full. For most systems this kit will work fine..
This kit is NOT for misting, ice maker line, line boosting, water transfer. This pump kit is designed for increasing water supply pressure to a RO water system.
