High speed shutter

“Compact & integrated”
size change and relocation are easy

  • space saving compact
  • easy relocation unit type
  • high speed fast opening /closing

Airtight structure that achieves high airtightness

The airtight seal on the winding section is highly effective against insects and dust, making it ideal for a variety of clean environments.

  • Airflow rate with a pressure difference of 10Pa *Conducted in accordance with JIS A 1516 at an in-house
  • Our products show values ​​with airtight seals.
  • Wind pressure resistance varies depending on size.

Characteristics

Evolved into ultra-high speed,
automatic return, quiet, durable,
and highly airtight.

Pipeless reborn faster, quieter and safer

Easily automatically returns the seat if it comes off due to a collision

Even if the lift or cart collides with the lift or cart during operation, it will stop, ascend at low speed (0.5m/sec), and automatically return to the rail. Even in the event of a power outage, it has a safe structure that even women can easily pass through by simply lifting the bottom end.

Industry’s fastest ascent of 3.2m/s, safe descent speed of 0.7m/s

Shorten opening time. It prevents insects and dust from entering, suppresses changes in indoor temperature and humidity due to the inflow of outside air, and contributes to improved quality, work efficiency, and energy savings.
*Opening/closing speed can be changed arbitrarily according to the application. Please refer to the specifications below for changeable speeds.

Operation noise reduced by 10% compared to conventional models! Quiet effect with Gateman tube

nstead of conventional zippers, gate tubes are used on both sides of the seat that are quieter and more effective at preventing damage. One-piece molding with fewer contact surfaces and less friction improves noise reduction.

  • Fewer contact surfaces and less friction (high durability, reduced dust generation and wear)
  • Integrated molding improves quietness (quiet performance, damage prevention)
  • Adopts a clover shape that does not easily come off.

  • Air tight seals can only be attached to the take-up box.

Characteristics

Pipe-type wind and pressure resistant
construction, ideal for insect, dust,
wind and cold protection

Fast-rising, airtight pipe type for small to large openings

Pipetype, resistant to wind and air pressure differences,and wind pressure-resistant specifications are also available in the lineup.

Reduced opening time. Contributes to improved quality, work efficiency, and energy conservation by suppressing changes in indoor temperature and humidity due to insect and dust infiltration and inflow of outside air.

Seals tightly by preventing gaps in the sheet caused by wind and differences in air pressure. Air-tight construction of the take-up box and side frames ensures high airtightness.

New engine adopted to achieve a high speed rise of 2.0 m/sec.

A new engine enables high-speed opening and closing at a rate of 2.0 m/sec. Shortens the opening time of the entrance and exit, and contributes to the improvement of the working environment by increasing the air conditioning effect as well as the insect and dust control effect.

Lower end pipe cushion structure

The cushion structure of the lower end pipe softens the impact of contact and prevents breakage, reducing maintenance costs.

Highly effective insect and dust control

Airtightness is further improved when used in combination with the Air Tight Seal.
Insects and dust are prevented from entering when the seal is fully closed, achieving higher quality control and a cleaner working environment.

  • Airflow rate at 10 Pa difference in atmospheric pressure
  • Conducted at in-house airtightness testing facility in accordance with JIS A 1516
  • The figures for our products are shown with air-tight seals.
  • Wind pressure resistance varies depending on the size.
  • Air tight seals can only be installed on the take-up box.
  • Air tight seals are made to order.

Highly visible and effective in saving electricity

SS clear sheet with higher visibility than conventional clear sheets.
Even when the shutter is closed, you can see what is going on on the other side and grasp the situation.
It also contributes to energy saving by keeping the room bright with its high lighting performance.
