OSHITARI Filtration Equipment & Systems
Explore the full product spectrum of Oshitari Laboratory precision filtration and cleanroom systems engineered for demanding industrial processes.
Oshitari OMF Filters for Wire EDM Machines
Manufactured to rigorous Japanese engineering standards, Oshitari Machine Filters (OMF) utilize proprietary multi-layer synthetic media that maintain structural integrity under elevated internal operating pressures. Compatible with leading wire EDM machines including Sodick, Fanuc, and Mitsubishi, they effectively reduce secondary spark discharge phenomena and extend deionizing resin longevity. The specialized non-woven media prevent fiber migration and eliminate soluble leaching into high-purity dielectric deionized water. Routine dielectric bath filtration prevents workpiece micro-pitting and stabilizes cutting speed across high-precision wire EDM cycles.

Machine compatibility: Direct fit for Sodick, Fanuc Robocut, Mitsubishi Electric, Makino, and Seibu wire EDM units
Oshitari HEPA & ULPA Absolute Air Filters
Drawing from pioneer breakthroughs in 1965 with Japan's first MIL-STD HEPA filter and the world's first ULPA filter in 1980, Oshitari absolute filters incorporate microglass fibers with mini-pleat hot-melt separators to achieve ultra-low pressure drop and certified 99.9999% particulate capture down to 0.1 µm. Every manufactured filter element undergoes individual laser particle counter leak testing and aerosol scanning before clean packaging. Precision separator placement eliminates turbulent eddy currents across the laminar discharge face, guaranteeing uniform velocity distribution in class 1 to class 100 clean rooms.

Oshitari Fan Filter Units (O·FU, O·FL, O·SU Series)
Engineered for semiconductor and pharmaceutical cleanrooms, Oshitari motorized fan filter units combine backward-curved centrifugal impellers with HEPA/ULPA filters. The ultra-quiet O·FL series integrates electronically commutated (EC) motors and aerodynamically optimized acoustic housings to keep sound power levels strictly below 48–52 dB(A). Built-in vibration isolation prevents structural resonance transfer to cleanroom ceiling grids. Variable speed controls provide adjustable air delivery from 0.35 to 0.55 m/s, meeting cleanroom energy-saving directives while maintaining constant static pressure profiles.
Module series: Motorized FFU units O·FU, low-noise acoustic series O·FL, and passive terminal filter units O·SU
Standard dimensions: 600x600 mm, 600x900 mm, 600x1200 mm, and 1200x1200 mm matching cleanroom T-Grid ceilings
Airflow velocity: Uniform laminar flow profile at 0.35–0.45 m/s with stepless speed control
Quiet operation: Advanced acoustic insulation in O·FL models limits sound power levels below 48–52 dB(A)
Network automation: Centralized multi-unit networking via RS-485 / Modbus communications for smart facility control
Oshitari Modular Clean Booths (O·AB, O·KB Series)
O·AB and O·KB modular clean booths provide rapid localized ISO Class 5 clean zones within standard factory environments. Featuring clear anti-static PVC curtains or rigid acrylic panels mounted on extruded anodized aluminum framing, they deliver positive-pressure laminar downward airflow. The modular construction allows swift relocation and expansion without disrupting facility production schedules. Optional HEPA or ULPA ceiling coverage can be customized from 25% to 100% depending on required cleanliness classes and localized heat loads.
