View supply scope and requirements
AC fan filter units
Ceiling fan filter units with conventional AC motors for cleanroom builders who need a lower-cost unit where individual or small-group speed control is enough and filters are replaced during routine maintenance.
Pre-filters
First-stage panel and pocket pre-filters in synthetic fibre, washable and high-temperature constructions, for air handling units serving commercial and industrial buildings.
VHP decontamination units
Vaporized hydrogen peroxide equipment in three unit types: fumigation pass boxes for small items, decontamination transfer rooms for large loads, and generators that supply sterilant gas to isolators, pass boxes and small rooms.
Medium-efficiency filters
Bag and rigid-case medium-efficiency filters (F5–F9 to EN 779) in synthetic fibre, glass fibre, panel and box constructions, for the middle stage of air handling systems.
Pulsed-light pass boxes
Pass boxes that disinfect items with intense pulsed xenon ultraviolet light while transferring them between clean and non-clean areas, reaching a high kill rate within minutes instead of the roughly 30 minutes a conventional UV pass box needs.
Booster fan filter units (BFU)
Ceiling blower filter units with a built-in fan for turbulent and laminar cleanrooms, bought by cleanroom builders who want a self-contained unit that filters and pushes air into the room without a remote air handling unit.
Low-resistance fine filters
High-medium-efficiency filters with very low initial resistance for ventilation systems with little spare fan pressure, such as hospital diagnostic and treatment rooms.
Slim-profile fan filter units (EFU)
Ultra-thin fan filter units about half the depth of a standard FFU for equipment-end local filtration in clean plants, bought where ceiling or equipment void space is limited and chemical outgassing must stay low.
Sub-HEPA (EPA) filters
Close-pleated sub-HEPA (EPA) panel filters on ultra-fine glass fibre or polypropylene paper, rated 95 % to 99.95 %, for cleanrooms and areas between medium and HEPA stages.
Airtight pass boxes
Gas-tight pass boxes with mechanically compressed doors, electromagnetic interlock and optional glove port, used where samples must move between zones without any leakage of hazardous agents.
W-type high-airflow sub-HEPA filters
W-shaped high-airflow sub-HEPA filters for central air conditioning and central ventilation systems, removing 1–5 µm particles at high airflow and low resistance.
Dunk tank transfer hatches
Pass-through chambers with a disinfectant basin, used in high-containment laboratories to move small acid- and alkali-resistant items through a liquid disinfection barrier between two rooms.
Gel-seal FFU
Fan filter units with a gel-seal filter fixing for high-grade cleanrooms, bought where the seal between filter and casing must block contamination reliably and where single units or bands of units sit above process points.
Mini-pleat HEPA filters
Separatorless mini-pleat HEPA panels of ultra-fine glass fibre paper with hot-melt pleat spacing, for terminal filtration in electronics, pharmaceutical and hospital cleanrooms.
Aluminium-separator HEPA filters
HEPA panel filters with aluminium foil separators between pleats of ultra-fine glass fibre paper, for terminal filtration where a rigid, corrosion-resistant pack is needed.
Explosion-proof FFU
Fan filter units in an explosion-proof construction for cleanrooms where flammable solvents, vapours or dusts are handled, bought by pharmaceutical, electronics and food plants that must keep air filtration running in a classified hazardous area.
Paper-separator HEPA filters
Separator-style HEPA panels with paperboard separators and polyurethane sealant in galvanised, stainless or aluminium frames, for terminal filtration in cleanrooms.
Portable clean-air supply units
Self-contained fan filter units for spot supply of filtered air in clean zones, bought to add a local clean-air point quickly or to back up an existing ceiling system in semiconductor, electronics, laboratory and hospital areas.
EC FFU group control systems
Central control systems that manage a ceiling of EC fan filter units from one point, bought with EC FFU projects in semiconductor, pharmaceutical and large cleanroom buildings where speed, monitoring and energy use must be managed together.
Gel-seal HEPA supply outlets
HEPA supply air outlets with a gel-seal channel that locks the filter frame against the housing knife edge for a leak-tight seal, in top-feed and side-feed versions with an optional regulating damper.
PTFE HEPA filters
HEPA and ULPA panels on PTFE membrane media for corrosive, high-temperature or copper-and-zinc-free duties where glass fibre paper is not suitable.
Two-side air showers
Personnel air showers with HEPA-filtered air jetted from nozzles on two sides, used at cleanroom entrances to remove dust from clothing before entry; the buyer's contractor positions and connects the cabin on site.
AC FFU group control systems
Central control systems that manage a ceiling of AC fan filter units from one point, bought with AC FFU projects in semiconductor, pharmaceutical and large cleanroom buildings where many units must run and be monitored together.
Three-side air showers
Personnel air showers that add top nozzles to the two side walls so filtered air blows from three directions, for entries where a more thorough dust removal is required; installed and connected by the buyer's contractor.
Negative-pressure weighing booths
Negative-pressure booths for weighing powder materials: a fan pulls air through primary, medium-efficiency and HEPA stages over the work zone, containing the powder and protecting the operator and the room.
FFU ceiling grid
Modular aluminium ceiling grid systems that carry FFUs, blank panels, lights and duct ends in a cleanroom ceiling, bought by cleanroom builders who want a demountable, reusable grid that can be cut on site and reconfigured later.
Knife-edge HEPA filters
HEPA panels with an integral knife-edge frame that pushes into a gel-filled sealing channel, for terminal positions where a gasket seal cannot guarantee tightness.
FFU blank panels
Close-out panels that seal unused FFU positions in a cleanroom ceiling grid, bought with FFU ceilings to keep unfiltered air out of the room, keep airflow even across the grid and leave a flat, cleanable ceiling plane.
Gel-seal HEPA filters
Mini-pleat HEPA panels with a gel potting groove around the flange, sealing against a knife-edge frame for terminal positions in industrial and biological cleanrooms.
Isolators
Rigid or flexible containment isolators that separate the work zone from the room with a physical barrier and controlled airflow: aseptic units for sterile operations, cell therapy units with integrated equipment, and negative-pressure units for potent or infectious products.
V-bank HEPA filters
Box-type HEPA filters with mini-pleat packs arranged in a V formation, giving high airflow capacity and low structural resistance in air handling units.
High-temperature HEPA filters
HEPA panels rated for continuous service at 250–280 °C or up to 400 °C, with stainless frames, aluminium foil separators and high-temperature sealant for ovens and hot process air.
Laminar flow transfer carts
Mobile vertical-laminar-flow units (sampling carts) that bring a local HEPA-filtered clean zone to the sampling or transfer point for raw and auxiliary materials in pharmaceutical production.
Activated carbon filters
Panel, box and W-type activated carbon filters that remove odours and gaseous contaminants by adsorption, for make-up air and recirculation in industrial ventilation.
Bio-seal and airtight dampers
Low-leakage airtight dampers for ventilation ducts in containment facilities, closing with a gas-tight seal so rooms can be isolated for decontamination and zero-leakage duty at a specified pressure difference.
Rapid roll-door cargo showers
Cargo air showers with rapid roll-up doors for high-frequency goods transfer into cleanrooms; door speed, curtain colour and control mode are fixed per configuration, and the buyer's contractor handles positioning and power on site.
Chemical filters
Panel, box and FFU chemical filters with adsorbent media for removing specific gaseous contaminants from process air, cleanrooms and fan filter units.
Mist showers
Mist showers that remove active or toxic dust adhered to cleanroom garments with a fine water mist before personnel leave a controlled area, installed between clean and non-clean zones.
Sliding-door cargo showers
Cargo air showers with automatic sliding doors for logistics corridors serving semiconductor, pharmaceutical and food plants; door sensing and the shower cycle are automatic, and the buyer's contractor positions and connects the unit on site.
