Description

An inspection hatch is an airtight access door installed on air ducts to provide quick and easy access to the interior of the system (for inspection, cleaning, or disinfection). We offer two types of solutions:

• For round ducts: The hatch has a curved (radius) frame profile, allowing it to fit tightly around the pipe.
• For rectangular ducts: The hatch has a flat frame for installation on the flat surface of a ventilation duct.

Key Features

• Airtightness: The hatches are equipped with an elastic gasket that ensures a high class of airtightness.
• Easy Installation: A self-adhesive cutting template is included. The hatch is secured with two rotating knobs, requiring no additional tools.
• Material: Galvanized steel (DX51+Z275). Stainless steel or aluminium versions available on request.

Technical Specifications and Article Numbers

Below are the compatibility tables and mounting hole dimensions for both types of hatches.

Hatches for round ducts (curved)

Hatches for rectangular ducts (flat)

Materials and Standards:

• Material: Galvanized steel DX51+Z275.
• Steel thickness: 0.7–1.2 mm (depending on size).
• Compliance: EN 1506:2007, PN-EN 12097.

Availability

• In Stock: We keep stock of hatches for pipe diameters from 100 to 500 mm.
• On Order: We manufacture hatches for large diameters (over 500 mm), as well as products made of stainless steel and aluminium.

Application and Installation

• Installation: The hatch is installed directly onto the duct wall (round or rectangular). A hole must be cut according to the shape of the gasket (dimensions $A times B$ are indicated in the table).
• Fixation: The hatch is inserted into the opening and tightened with the rotating knobs, which ensure secure fixation and airtightness.
