Multi-purpose FRP fans compatible with a wide range of exhaust applications.

The industry’s first FRP sirocco fan manufactured using injection molding technology. Achieves stable quality, high performance, and shorter delivery times.
Through FRPP injection molding technology, these fans provide superior performance and ease of use. Compared with conventional chemical sirocco fans, the maximum average static pressure has been improved by 150 Pa (based on our company comparison). With the newly developed one-piece FRPP molded structure, both performance and usability have been significantly enhanced.

A sirocco fan designed to maximize low cost, short delivery time, and space-saving performance.

A turbo fan covering the medium-pressure range (static pressure: 450 Pa to 1400 Pa). The casing is made from molded FRPP, while the impeller uses highly corrosion-resistant FRP materials. Designed to achieve low cost and short delivery times.
Supports static pressure from 450 Pa to 1400 Pa with short delivery time, low cost, and high corrosion resistance. A turbo-type fan designed for medium-pressure applications (450 Pa to 1400 Pa static pressure range). The casing is made of molded FRPP (glass fiber reinforced polypropylene resin), while the impeller uses highly corrosion-resistant FRP with excellent mechanical strength. Even after installation, the discharge direction can be freely adjusted in 30-degree increments. Provides high dust collection efficiency.

The unit is equipped as standard with our original KS5-O Type / Hertz Master exhaust fan, which has earned strong trust and a proven track record for its high performance, energy efficiency, and low operating cost. Combined with an FRP soundproof cover designed with a strong focus on appearance and lightweight construction, this BOX fan reduces fan noise while creating a softer appearance that blends well with surrounding environments. Suitable for a wide variety of applications, including universities, private and public research institutes, apartment disposer exhaust systems, hospitals, and other facilities requiring harmony with surrounding environments.

These are turbo fans available in two types: the V-belt drive type RFT-RB and the direct motor-coupled type RFT-OA. Both models are designed with a strong focus on high efficiency and energy savings. In particular, the RFT-OA type has achieved over three years of continuous non-stop operation.
The RFT Series is an ultra-high-efficiency FRP turbo fan that delivers excellent corrosion resistance, heat resistance, impact resistance, and high-pressure performance. At the same time, it minimizes power loss and vibration while significantly reducing power consumption. Suitable for both exhaust and air supply applications across various industries, the RFT Series promotes energy savings and contributes to substantial CO₂ reduction.
