Access door RD 64 - V2A

Corrosion-resistant stainless steel access door for durable air ducts

The REVISION RD 64 – AISI 304 is a tried-and-tested stainless steel access door for rectangular, uninsulated air ducts. This access door has been specially developed for long-term use in professional air duct installation. Thanks to the duct wall clamping mechanism, whereby the duct wall is clamped between the inner and outer covers, and the integrated PE seal, the access door meets the airtightness requirements of ATC2 in accordance with DIN EN 16798-3. This also ensures reliable access for inspection, maintenance and cleaning work. The AISI 304 stainless steel version offers high corrosion resistance and is particularly suitable for demanding environmental conditions.

In day-to-day operations, operators, service companies and duct installers are frequently faced with the challenge of having to inspect ventilation systems on a regular basis. In doing so, the airtightness of the air duct system must not be permanently compromised. The REVISION RD 64 – AISI 304 solves this problem thanks to its robust stainless steel construction. It also features corrosion-resistant and ergonomic POM twist handles with a maximum clamping force of 2,000 to 3,000 Nm, as well as a durable PE seal. This ensures that the inspection opening remains reliable even after numerous maintenance cycles.

PE seal for reliable sealing in air duct construction

The integrated PE seal consists of a closed-cell, cross-linked polyethylene foam and ensures reliable sealing between the access door and the duct wall. The seal is available in a white finish and features a self-adhesive backing, facilitating simple and clean installation. Furthermore, the material is REACH-compliant and free from substances of very high concern in accordance with current REACH requirements.

The PE seal is designed for a temperature range of -40 °C to +70 °C and can withstand temperatures of up to +80 °C for short periods. This makes it suitable for numerous applications in ventilation and air-conditioning technology.

In terms of resistance to liquids, the PE seal offers limited protection against splashing water. For applications with increased requirements for liquid tightness, the specific operating conditions should be checked and, where necessary, alternative seal variants considered.
