Double Poly Greenhouses with inflation pressure between layers were flrst developed at Rutgers by Dr. Bill Roberts. The air space between the layers of polyethylene provides insulation without blocking sunlight. This innovation has allowed growers in cool regions to extend their growing seasons by saving up to 40 % of their energy costs.

The Ken-Bar Inflation Units are designed to pressurize these greenhouses. All the components for a complete installation are included in one carton.

Product Description: These inflation units are available with either 148 or 60 cubic feet per minute blowers and as a single or a double unit. All units have top hats for entering the poly, blower mounting boards, and 4- foot flexible ducts. Installation instructions are provided. The 148 CFM units should be used to inflate houses over 60 feet long. The 60 CFM blower will handle smaller houses.

OUTSIDE AIR KITS

Kits are available for both the 60 and 148 CFM units to provide an outside source of inflation air. There may be times when outside air is a better input between poly layers than inside air. Outside air is gener-ally a better choice when it is dryer than the greenhouse air. This occurs during cooler weather when moist inside air cools off between the layers and the moisture condenses on the outside sheet, obstructing light. The use of outside air kits will minimize moisture build-up between the poly layers.

Product Description: These outside air kits attach to the intake port of the inflation units. A 4-foot duct and a screened top hat are also provided.

JUMPER KITS

Jumper Kits are designed to pass pressure from one sction of double poly to an adjoining section.

Product Description: Two twist couplers on each end of a 42" hose of 1.5" diameter.
