Cover for air blower without lid HL905N.0, grey color, snap-on HL905.4

Sanitary installation air vent – comfort and protection

This element is a practical solution for installers and users who value trouble-free operation of the sanitary installation. The masking cover for the HL905N air vent, in gray color, is designed for flush-mounting in walls with a depth of 75 mm. It provides an aesthetic appearance and easy access to the air vent valve if necessary.

Functionality and application

The HL905N air vent, in combination with this cover, eliminates problems with gurgling, siphoning, and unpleasant odors from the sewer system. This is particularly important in installations with remote sanitary appliances (more than 4 meters from the drain pipe) and in systems built with dry construction. Thanks to the flat design of the valve, installation is simple and does not require additional procedures, such as creating recesses or housings.

• Pressure equalization: Ensures proper ventilation of the installation, preventing problems with drainage.
• Easy access for inspection: Removable functional element allows quick access to the installation for cleaning or maintenance – even with a spiral.
• Aesthetic appearance: The masking cover hides the air vent valve, leaving only a discreet finishing element on the wall. The ability to replace the cover with a different color allows you to match it to the bathroom decor.
• Versatility: Designed for walls in dry and wet construction.
• Compliance with standards: Meets the requirements of PN - EN12380 - A1 and PN - EN12056 - 2.

Construction and installation

The cover is made of durable ABS material, which guarantees its resistance to mechanical damage and long-term use. Installation is simple and intuitive – the cover is placed on the housing of the HL905N air vent valve. Additional brackets facilitate connecting the valve to the profile in the drywall. The entire system has been designed to make the installation process as non-invasive to the wall and as comfortable as possible for the installer and end user.
