500mm Window Actuator Wide Rapid Cooling Window Opening For Smoke Exhaust

GL500 High-Performance Window Actuator | Wide 500mm Opening for Smoke Exhaust & Rapid Cooling

Product Overview

Maximize Airflow for Large Spaces.

When you need serious ventilation, the GL500 is the answer. Engineered with an extended 500mm stroke, this actuator pushes windows wide open to rapidly flush out heat, smoke, and odors—making it perfect for high-ceiling warehouses, commercial lofts, or large atrium skylights.

It combines a massive 500N lifting capacity with superior reach. Built on a global AC90-240V platform with RS485 compatibility, the GL500 acts as a critical component in building climate control and passive smoke exhaust strategies. When closed, the stainless steel chain locks tight to guarantee storm-proof security.

Key Features

• Extended 500mm Reach The extra-long chain extends a full 500mm, significantly increasing the ventilation area. This is critical for chimney effect cooling in summer or rapid smoke clearance in emergencies.

• Ideal for Tall and Heavy Windows The longer stroke is specifically optimized for taller top-hung windows or heavy curtain wall sashes that require a wider opening angle to be effective.

• Commercial Grade Durability Tested for over 30,000 cycles, the GL500 uses a double-link stainless steel chain designed to maintain rigidity even at full extension, ensuring stability in commercial environments.

• Smart Automation Ready Standard with RS485 for BMS integration. Optional upgrades allow for connection to wind and rain sensors, automatically closing the large opening during storms to protect the interior.

Specifications

FAQ:

Q1: Why should I choose the GL500 over the GL300?

A1: The GL500 features a longer 500mm chain extension, which pushes the window open wider than the GL300. This is essential for large skylights, commercial windows, or smoke exhaust applications where maximum airflow and rapid heat dissipation are required.

Q2: Does this motor work with a smart home app?

A2: The standard version is a 5-wire motor designed for wired wall switches or RS485 systems. If you want to use the Smart Life App, you must select the optional WiFi or Zigbee version when purchasing to ensure the wireless module is included.

Q3: Can this motor handle heavy double-glazed windows?

A3: Yes. The GL500 delivers a push/pull force of 500N (approx. 50kg). It is powerful enough to operate most heavy residential skylights and commercial curtain wall windows securely.

Q4: Can I connect a rain sensor to automatically close the window?

A4: Yes, but this requires the unit to be equipped with the optional wireless receiver. Once connected to a compatible wind/rain sensor, the GL500 will automatically close the window when rain is detected to protect your interior.
