695 mm Black Hood Air Inlet

Product Overview

This black hood air inlet is a wall-mounted fresh air intake used on poultry houses that rely on mechanical exhaust ventilation. Instead of letting wind and rain hit a bare hole in the side wall, the hood covers the opening, directs incoming air gently along the ceiling, and keeps the rain out of the house. The unit shown is moulded entirely in black engineering plastic, with a flat mounting flange on the back that carries several fixing holes for screws or bolts through the wall.

The printed dimensions on the drawing give a clear idea of the size: 695 mm across the top, 365 mm in overall height, with a 290 mm body depth and a 565 mm lower edge projection. The curved hood shape shields the opening from driving rain while the open underside and back let fresh air enter evenly. It is a low-maintenance piece of environment control hardware with no fans, motors or moving parts.

Key Features and Benefits

• Rain-shielding hood shape - the curved black cover keeps rain and snow out of the side-wall opening during storms.
• Mounting flange with fixing holes - the flat rear flange lets installers bolt the hood straight to a wooden or concrete wall.
• No moving parts - no fans, motors or belts to service; the hood works passively with the house exhaust system.
• All-plastic black body - the hood resists outdoor weathering and will not rust like a metal vent.
• 695 mm wide flow path - the wide inlet spreads the incoming air over a long stretch of wall for even distribution.
• Low maintenance - wash the hood down between flocks; there is nothing to oil, adjust or replace.

Materials and Quality

The hood is moulded from thick black plastic chosen for outdoor exposure, because it sits on the outside wall and faces sun, rain and temperature swings every day. The wall flange is rigid and drilled with fixing holes at the factory, so installers do not need to measure and drill the plastic on site. The curved shell resists impact from grazing animals and from cleaning poles, and the matte black finish stays functional through years of UV exposure without paint to touch up. Because the hood projects out from the wall, rain running down the shell drips away from the opening instead of funneling back inside, which is the detail that keeps the litter dry even in long storm seasons.

How to Use and Maintain

Mark the opening on the side wall of the house, fix the hood flange in place with suitable screws or bolts, and seal the edge against rain with a strip of sealant if your wall needs it. Position the hood so the open underside faces the incoming air path set by your exhaust fans. Between flocks, rinse the shell with water to wash off dust and cobwebs, and check that the fixing holes are still tight. there is nothing that can jam or wear out. Position the hoods opposite the exhaust fans wherever possible, so the air path crosses the whole house length and every bird zone gets fresh air rather than only the wall nearest the fan. Even spacing along the wall prevents dead corners.

Applications

This hood inlet is installed on the side walls of closed poultry houses where exhaust fans pull air out and fresh air must enter in controlled amounts. It suits meat-chicken houses, breeder sheds and layer barns that need passive air inlets matched to tunnel or minimum-ventilation fan programs. Because the hood keeps rain out, it is also used in rainy regions where a bare wall opening would drip water onto litter or birds.

It works well on both new builds, where the flange holes line up with the planned wall openings, and retrofits on older sheds that need a simple, rust-proof replacement for aging metal vents. Distributors can stock it as a standard side-wall inlet accessory alongside exhaust fans, cooling pads and controllers, since every fan program needs matched air inlets to balance the house.

Frequently Asked Questions

Q1: Does this hood include a fan or damper?

No. This is a passive wall hood: it covers and protects the wall opening, while the exhaust fans inside the house pull the air. No power or control wiring is needed for the hood itself.

Q2: Can it be mounted on a concrete wall?

Yes. The flange has fixing holes, so installers bolt it to timber walls with screws or to concrete and block walls with suitable plugs and bolts.

Q3: How many hoods do I need per house?

The number depends on your fan capacity and house length. Send us the fan size and house dimensions, and we can suggest an inlet layout to balance the system.

Q4: Will the black plastic get hot in summer sun?

The shell is exposed to sun, but the inlet air passes through the open gap rather than heating inside the house. The material is selected for outdoor weathering and stays intact through normal summer exposure.
