Exhaust/ventilation grille DOSPEL KRATKA KRZ 150

DOSPEL KRATKA KRZ 150 is a ventilation and exhaust grille designed for integration with residential and commercial HVAC and exhaust systems where a 150 mm duct connection is required. The grille provides a defined inlet or outlet for air exchange, allowing connection to circular ducts or wall openings. Its simple form is intended to fit standard installations and to ensure unobstructed airflow between rooms or to the exterior when paired with matching ductwork.

Advantages

The DOSPEL KRATKA KRZ 150 grille offers straightforward installation and compatibility with 150 mm circular duct systems. Constructed to provide stable airflow and to interface with common ventilation components, it reduces the need for custom adapters. The design focuses on functional performance, ensuring consistent air exchange and easy maintenance access when installed in walls or ducts.

Suitable for

• Residential ventilation systems requiring a 150 mm connection
• Commercial or light-industrial exhaust installations with standard circular ducts
• Wall or ceiling openings serving as supply or extract points
• Integration with bathroom or kitchen exhaust fans connected to 150 mm ducts

Key specifications

• Connection diameter: 150 mm compatible with circular ductwork
• Application: inlet or outlet grille for ventilation and exhaust systems
• Installation type: wall or duct-mounted depending on site conditions
• Material: rigid construction suitable for HVAC use (finish appropriate for typical indoor environments)

How to use

Install the grille at the prepared opening or duct end sized for a 150 mm connection. Ensure the duct or wall sleeve is cut square and clear of obstructions before attaching the grille. Fasten the grille securely to the wall, ceiling or duct flange using appropriate screws or fixings for the substrate, and seal joints as necessary to prevent air leakage. Connect to the ventilation or exhaust fan and check airflow direction to confirm correct operation.

Usage recommendations

Periodically inspect and clean the grille to prevent dust buildup that can reduce airflow. When replacing components in an existing system, verify compatibility of duct diameter and airflow direction. Use suitable sealing materials at joints to maintain system efficiency and reduce noise transmission.
