Compact Water-Curtain Extraction Wall Aspiration System Hydro 1 (ASH1)
In Stock
The Aspiration System Hydro 1 is the most compact water-curtain extraction wall in the series, with three-stage filtration — a water curtain and a final PaintStop filter — a manual 450 × 450 mm turntable and an IP66-rated LED luminaire for coating small products and parts. The water filtration stages capture up to 90 % of paint overspray particles, so the final filter requires less frequent replacement than in dry filtration systems.

The Aspiration System Hydro 1 is the most compact water-curtain extraction wall in the Aspiration System Hydro series. It helps create safer and more comfortable working conditions in the paint shop during surface preparation and coating application on small products and parts made of wood, metal, plastic and other materials. Its key feature is water filtration: the water curtain captures up to 90 % of paint overspray particles and aerosols, so the final filter requires replacement much less frequently than in dry filtration systems, while the turntable allows the product to be coated from all sides without repositioning it.
Installation requires no preparatory construction work: only exhaust ducts need to be connected, so the wall can be installed quickly in almost any room.

How It Works
The painter places the product on the turntable in the working zone, and the ventilation unit draws air through the working zone at 0.25–0.4 m/s. Air carrying paint overspray passes through two stages of water filtration, where up to 90 % of the coating particles are captured by the water. It then passes through a PaintStop fibreglass filter before being discharged outdoors through the exhaust ductwork.

The circulation pump feeds water from the tank to the water curtain and the spray nozzles, and the water is recirculated in a closed loop. The 0.45 × 0.45 m table rotates through 360°, so the product can be turned to the required side without removing it from the table.
Three-Stage Filtration
Working zoneWater curtainWater spray nozzlesPaintStop EU4 filterVentilation unit and exhaust
The first stage is a water curtain 0.9 × 1 m: water flows evenly down the overflow plate and washes away paint overspray. The second is water spraying through two nozzles, which precipitates paint particles into the water. The third, an EU4-class PaintStop fibreglass filter, provides final filtration. Together, the three stages provide a filtration efficiency of at least 95 %.
Because most of the overspray is captured by the water, the PaintStop filter is loaded far less than in dry filtration systems, resulting in longer replacement intervals and lower maintenance costs. The fibreglass filter area is 0.41 m², with a paint-holding capacity of approximately 3.5 kg/m² depending on the coating material.
Typical Applications
Paint shops in furniture workshops and factories, frame workshops, light industry and small metal product manufacturing.
Paint colour-matching laboratories.
Small products and parts — especially where a clean working environment and high coating quality are required.
Intensive painting — water filtration captures far more paint than dry filters, so the final filter needs replacing less often.
Construction
Housing — upper housing made of 1.5 mm sheet steel with an 18–40 µm zinc coating and a powder-coated top cover; tank, gratings and table made of 2 mm sheet steel.
Water filtration — water curtain with an overflow unit and overflow plate, two water spray nozzles and a water circulation system with a 0.75 kW drainage pump delivering 225 L/min.
Final filter — filter cassette with a 0.41 m² EU4-class PaintStop-type fibreglass filter.
Ventilation unit — medium-pressure centrifugal fan with a 0.75 kW, 1,500 rpm asynchronous motor; 140 × 140 mm outlet.
Turntable 0.45 × 0.45 m on a 360° swivel bearing, plus a spray gun holder.
Lighting and control — 18 W LED luminaire, IP66, control panel, electrical installation kit and set of fasteners.
Safety and Installation
The equipment is approved by the State Labour Service of Ukraine for use in Ukraine.
A version for potentially explosive atmospheres is available on request: a fan made of dissimilar metals or aluminium, with an explosion-proof motor, control panel and luminaire.
Power supply: 3-phase, 380 V, 50 Hz; with a variable-frequency drive, the wall can be connected to a 230 V supply.
Exhaust ducts: total length to the discharge point no more than 10 m, cross-section at least 0.05 m².
The explosion-proof control panel requires a compressed-air supply of 1.5–2 bar, up to 100 L/min.
Custom Configuration
The extraction wall can be supplemented with:
Side deflectors made of galvanised steel — installed at 45°, they extend the extraction zone by 250 mm in height and 500 mm in width and keep overspray within the wall area.
Active water floor — an additional 1,000 × 330 mm section (width to match the wall) connected to the wall tank: water flows under the floor gratings and carries away excess paint. Up to three sections can be used; an additional 2 kW pump is installed, and the gratings take a maximum load of 218 kg over a 200 × 200 mm area.
Mini booth with product rotation mechanism — mounted on the top panel of the wall, it allows products to be suspended and rotated directly in front of the extraction zone.
Motorised turntable.
Stainless-steel overflow plate instead of galvanised — water flows more evenly and the plate lasts much longer.
Airflow control system based on a variable-frequency drive — up to 40 % reduction in power consumption, required air velocity maintained as filters load, and the option of a 230 V supply.
Duct kit for connecting the ventilation unit, mounted on the wall next to the extraction wall or on the floor to its right or left.
Housing finish — powder coating in any RAL colour or stainless steel instead of galvanised panels; the internal housing components can also be made of stainless steel.
Manufacturing time: up to 12 working days; version for potentially explosive atmospheres: up to 40 working days. Warranty: 12 months.
