Secure a CF Backdraft Damper to your inline ventilation system to keep exhausted air out for good. When used in conjunction with a Can Fan and carbon Filter, the CF Backdraft Damper also helps control odors as it prevents any untreated air from escaping the enclosed area. Secure the directional damper downstream from your fan: when the fan turns on, the airflow opens the damper, and when the airflow stops, the damper closes. This 14” CF Backdraft Damper fits any standard 14” ventilation ducting.

For fitting in circular ducts. Made from pre-galvanized steel with spring-loaded vanes of aluminum, the backdraft shutter can be fitted in any position.

CarboLoad was the first and is still the best carbo booster for plants. Our scientists were the first to make a guaranteed organic formula that fixes carbohydrate depletion so hydroponics plants give big, sweet harvests.

Our 100% organic CarboLoad Liquid and Powder gives your indoor plants the extra energy they need for better harvest production right away.

CarboLoad has all the essential sugars plants need for maxed out, energy-rich health and bloom. This formula is guaranteed easy to use, combines perfectly with other bloom additives, fits well with an all-organic feed program, and is very effective at maintaining growth and improving flavor.

Only CarboLoad is guaranteed to be easily absorbed and instantly available so plants rock n’ roll to give you what you grow for. Carbo Load gets rid of carbohydrate depletion. You get better bloom production for larger harvests faster.

For fitting in circular ducts. Made from pre-galvanized steel with spring-loaded vanes of aluminum, the backdraft shutter can be fitted in any position and is available in the following diameters: 4", 6", 8", 10" 12" and 14".

Suncourt Motorized Dampers also known as Zone Dampers, Motorized Duct Dampers, or Automatic Dampers are mounted in ductwork to automatically shut off or open branches of the duct to airflow. They are available in normally open (power close) or normally closed (power open) configurations.

• Zone Control-Do you have a spare bedroom that you don’t want to fully heat or air condition because the room is rarely used? A Zone Damper will shut off air to that room’s registers and only allow air to flow again when temperatures in that room exceed or drop below your preset temperature. Zone Dampers are typically controlled by a thermostat or some type of master controller. Likewise Zone Dampers can control airflow to whole sections of a home or building to regulate temperature in those specific areas at certain times of the day, evening or the time of your choosing, which saves on heating and cooling bills.
• Ventilation-Zone Dampers can open to allow temporary ventilation of homes, garages, greenhouses, or other rooms where fresh air intake or stale air outtake is required.

Suncourt Automatic Dampers are 24-volt powered and require a transformer. Suncourt Zone Master Dampers are often installed by homeowners and have a transformer included in the box.  Automatic Dampers can be wired to 24-volt thermostats. Suncourt Automatic Dampers feature a soft-stop, freewheeling coupling between the motor and the damper shaft, which greatly improves life over other similar style dampers on the market. Suncourt Automatic Dampers feature a hysteresis motor that is designed to hold the damper closed or open with power indefinitely.
