HIRT Kinetics® HF-75

Compact. Seamless. Elegantly Engineered.

The HIRT kinetics HF 75 is the more compact counterpart to the HF 90 — a sleek window system that sits flush with the building’s exterior and offers two opening options: upward or downward.

True to HIRT’s engineering standards, the HF 75 is counterweight-balanced for smooth, effortless movement. Its lightweight design allows it to be easily operated by hand, while an electric motor option is available for added convenience. Built-in safety features, including a drop stop mechanism, ensure secure and reliable operation at all times.
