Hydrofilter for Barbecue and Josper Ovens

Air Purification for Restaurants and Businesses

For many years, professional kitchens have embraced the use of open flame cooking.

The taste of dishes prepared over live fire evokes nostalgia - reminding us of traditional meals baked in a wood-fired oven, picnics in nature, or childhood holidays at our grandparents’ home.

Or, quite simply - it tastes incredible.

No electric appliance can deliver that distinctive flavour.

When we cook over fire, we don’t just prepare food - we sell memories and emotions.

When using charcoal - or wood-fired equipment in a professional kitchen, it is essential for every restaurant to install systems that promptly extinguish sparks and purify the air.

A hydrofilter for a grill or oven serves both as an air purifier and a fire-prevention unit.

Smoke and soot from the grill enter the ventilation system. Without a hydrofilter, grease and soot gradually build up inside the ducts, creating a serious fire hazard from accidental sparks.

To prevent this, the grill or oven must be connected to the restaurant’s ventilation system through a hydrofilter - a water-based filtration unit.

Inside the hydrofilter, sparks are completely extinguished, soot and grease particles are captured, and the air and smoke are cooled to a safe temperature.

Therefore, a hydrofilter installed in a restaurant’s flue or chimney is essential equipment that should be purchased together with any grill, Josper, or other solid-fuel oven.

Modern diners do not wish to eat surrounded by smoke and fumes, as in an old tavern or medieval inn.

Comfort, cosiness, and safety should be the guiding principles of every restaurateur.

That’s where we come in - providing professional air-purification equipment for restaurants.

We offer advanced technological solutions for removing soot, sparks, smoke, odours, grease, and other impurities from the air.
Our equipment ensures fire safety, eliminates unpleasant smells, and keeps the kitchen air clean and safe for both staff and guests.

How Does Air Purification Work?

A mixture of flame, hot carbon dioxide, smoke, and soot particles bursts out from the grill or the open doors of the oven - and is immediately drawn into the ventilation system.

To prevent the ventilation system from being damaged by the hot gases, or from igniting due to soot deposits that should never accumulate inside, a hydrofilter is installed.

The heated gases containing solid particles first enter a dense water curtain created by multiple high-pressure nozzles. This looks like a mist, but with much greater density.

Such a strong and impenetrable water curtain is unique to our equipment - because we have conducted extensive testing to determine the optimal pressure and nozzle configuration. The result is a system that guarantees complete protection from combustion products.

All unwanted substances are then trapped in the water, which is drained into the sewage system once a day.

The air continues its journey towards further filtration.

Removable ceramic cassette filters capture dispersed hot grease and smaller particles from the gas mixture.
Why removable cassette filters? Because they make maintenance much easier and keep the hydrofilter convenient to service.

The ceramic filters can be taken out and washed as needed - typically once a month, although the frequency depends on your specific kitchen operations.

Since our systems use a high-pressure water curtain, droplet separators are installed at the outlet to prevent water leakage into the air ducts and to provide additional gas filtration.

As a result, the air leaving the unit is dry, comfortably cool, and contains only a minimal trace of smoke.

If complete smoke elimination is required, we recommend installing an electrostatic filter, which we also supply.
And for total removal of kitchen odours from the ventilation outlet, we offer a professional industrial ozone-based air purifier.

Service windows are conveniently located along the gas path for easy maintenance.
The entire process is controlled electronically, using data from sensors and measuring devices.

A key feature is the automatic washing system - it can operate even while the equipment is running.
By the time your restaurant closes for the evening, the hydrofilter is already clean and ready for the next shift.

Thanks to their powerful air-purification and spark-suppression systems, our hydrofilter spark arrestors are used not only in the restaurant industry but also in various industrial facilities.

We also collaborate with ventilation and engineering companies.
