Nekos Sky450 rack actuator

The Nekos Sky450 stands as a premium Italian-engineered solution for high-load window automation. Specifically designed for skylights, domes, and large top-hung windows, this rack-and-pinion actuator delivers a formidable 450N thrust and pull force. Its robust construction, featuring a glass-fibre reinforced polyamide housing and a high-strength steel rack, ensures peak performance in demanding commercial and industrial ventilation environments where reliability is non-negotiable.

Quick Answer

The Nekos Sky450 is best used for automating heavy domes, skylights, and top-hung windows that require high mechanical resistance and long stroke lengths (up to 1000mm) beyond the capacity of standard chain actuators.

✓Powerful 450N thrust/pull force designed for heavy architectural glass and domes.
✓Versatile stroke range from 180mm up to a market-leading 1000mm extension.
✓Dual-voltage compatibility (110-230V AC) for international installation flexibility.
✓IP44-rated weather resistance ensures durability against dust and water splashes.
✓Reinforced glass-fibre housing paired with an anodized steel rack for maximum structural integrity.

Choose the Nekos Sky450 if you are managing a project with heavy skylights or industrial domes that require a vertical lift of up to 1000mm. Its 450N force rating makes it the definitive choice for windows that are too heavy for standard actuators.

✓ Who Should Buy

  • •Commercial facility managers looking for durable dome ventilation solutions.
  • •Architects specifying heavy-duty actuators for large-scale glazed facades.
  • •Industrial contractors needing a high-thrust motor with wide voltage compatibility.

✕ Who Should Avoid

  • •Residential users with small, lightweight side-hung windows where a chain actuator is more space-efficient.
  • •Projects requiring silent operation in sensitive areas, as rack actuators produce more mechanical sound than chain alternatives.
Product Overview
The Nekos Sky450 is a precision-crafted linear actuator that bridges the gap between residential convenience and industrial power. Unlike traditional chain-driven systems, the Sky450 utilizes a rigid rack-and-pinion mechanism, providing superior stability and the ability to withstand significant wind pressure or gravitational loads on horizontal openings. Its sleek silver/grey anodized casing allows it to integrate discreetly into modern building envelopes without compromising on aesthetic standards. Operationally, the Sky450 is designed for longevity. The motor speed of 6.7 mm/s provides a controlled, smooth opening sequence, ideal for managing natural ventilation in large halls, warehouses, or high-end residential skylights. The sliding clamp mounting system allows for adaptable installation across various frame profiles, making it a favorite among professional installers for its 'fit-and-forget' reliability.

Engineering Analysis
The technical architecture of the Sky450 focuses on 'Force vs. Stroke' optimization. By utilizing a rack-and-pinion drive, the actuator avoids the lateral play often associated with long-stroke chain motors. The inclusion of a safety stop mechanism protects the internal gear train from torque-overload, significantly extending the lifecycle of the motor. Furthermore, its wide operating temperature range (-5°C to +65°C) validates its use in diverse climates, from cold skylights to high-temperature industrial exhaust points.
