アライ実業 List of Products and Services

The "SB Belt" (shown in the photo) for duct components is used to connect flexible ducts to spiral ducts or short pipes of air supply boxes. It can be tightened with common tools such as a screwdriver or hex wrench. It can be easily removed and reused with a one-touch mechanism. The "Plate Band" is cheaper than the SB Belt and offers more flexibility in size. For diameters of 450mm or more, please connect and tighten two M-sized bands. The "Hanging Band" is a dedicated component for suspending flexible ducts. With a width of 50mm, it does not dig into the flexible duct. Additionally, we offer nipples, fixing collars, and branching boxes. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust
• Piping Materials

The bifurcation-type flex, Souterflex, is a flexible duct that incorporates a branching branch pipe, eliminating the need for the branching box traditionally used in construction methods. Insulation work (band wrapping work) after duct connection is also unnecessary, contributing to a reduction in labor and construction costs. You can choose from various specifications based on flexible ducts manufactured by Arai Jitsugyo Co., Ltd., both for the external covering and the inner surface. Examples of main pipe end processing include reducer processing, single drop pipe installation, and closed processing. It is also possible to set up three or more branch pipes. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust

Flexible duct for ventilation (without insulation) is compatible with high-pressure systems (below +2500Pa) and can be used for exhaust and ventilation of moisture and chemicals. The galvanized copper wire is also sealed within the sheet, making it resistant to corrosion. Silverflex AD-2 uses a sheet with aluminum vapor-deposited on a PET film substrate. Hyperflex HY (shown in the photo) is molded by thermally bonding a PVC (polyvinyl chloride) coated sheet. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust

The flexible duct with condensation prevention (high insulation) JIB-W-S and Al-Jib-Flex AL-JIB-W-S (shown in the photo) are designed with a PET film wrapped between the non-woven fabric on the inner surface and the insulation material GW, preventing internal moisture from penetrating into the GW. Please use them in systems with high humidity or where insulation is particularly necessary, such as countermeasures against crosstalk in outside air intake ducts. They also provide moderate soundproofing effects. The Al-Jib-Flex AL-JIB-W-S prevents pinholes caused by welding sparks during installation due to its aluminum-coated outer surface. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust

The flexible duct for high pressure 2 (up to +2500Pa) prevents internal moisture from penetrating the GW and has excellent corrosion resistance. It is ideal for exhaust and ventilation systems dealing with chemicals and humidity. The Silverflex AD-G/AL-AD-G (shown in the photo) uses PET film coated with aluminum on the inner surface, making it suitable for the primary side of VAV and clean rooms. Additionally, the Hyperflex HY-G is formed by thermally bonding a PVC (polyvinyl chloride) coated sheet to the inner surface. The Hyperflex AL-HY-G prevents pinholes caused by welding sparks during installation due to its aluminum coating on the outer surface. It also uses a PVC (polyvinyl chloride) coated sheet on the inner surface. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust

The flexible duct for high pressure 1 (up to +1000Pa) SL Flex SL/SL-A (as shown in the photo) can be used for high pressure system 1 (below +1000Pa) and is ideal for humid systems due to improved moisture resistance. It uses a polyester film on the inner surface, preventing internal moisture from penetrating into the GW. Additionally, the galvanized steel wire is sealed within the film, making it resistant to corrosion. The SL-A has weld resistance due to its aluminum-coated outer surface. For more details, please contact us or refer to the catalog.

• Ventilation and Exhaust

The flexible duct for general low pressure is an environmentally friendly product as it does not use PVC or adhesives. The Jibflex JIB (shown in the photo) is a standard type of flexible duct offered at the most reasonable price range. It is available in lengths of up to 10 meters, with diameters ranging from a minimum of 50 mm to a maximum of 500 mm. The Aljibflex AL-JIB uses aluminum-coated PET film for its outer covering material, which prevents pinholes caused by welding sparks. It is a durable outer woven covering material that is difficult to damage during on-site construction. For more details, please contact us or refer to the catalog.
