Hydrofilter for barbecue and hosper

Air Purification for Restaurants and Businesses

The use of live flames for cooking has long been popular in the kitchens of modern restaurants.

The taste of such dishes evokes nostalgia - reminding us of times gone by, of food cooked in an oven or over an open fire, of outdoor gatherings and holidays at our grandparents’ home.

Or simply - it’s incredibly delicious!

No electric equipment can replicate that unique flavour.

When we cook over fire, we’re not just serving food - we’re selling memories and experiences.

However, when using thermal equipment in a kitchen that runs on coal or wood, it is essential for the restaurant to install proper systems to extinguish sparks and purify the air in a timely manner.

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

Smoke and soot enter the ventilation system from the grill. Without a hydrofilter, layers of soot gradually accumulate inside the air ducts, increasing the risk of fire caused by an accidental spark.

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

The hydrofilter completely extinguishes sparks, traps soot and grease particles, and cools the air and smoke to a safe temperature.

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

Modern restaurant guests do not wish to dine surrounded by smoke, fumes, and carbon monoxide, as in an old tavern or medieval inn. Comfort, cosiness, and safety should be the guiding principles for every restaurateur.

And we can help achieve this by providing professional air purification solutions for restaurants.

We offer advanced technological systems for removing soot, sparks, smoke, odours, grease, and other impurities from the air. Our equipment ensures fire safety, eliminates unpleasant smells, and maintains clean, breathable air in every kitchen.

How Does Air Purification Work?

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

To prevent the system from being damaged by these hot gases, or from igniting due to accumulated grease deposits, a hydrofilter is installed. Its purpose is to protect the ventilation ducts and ensure safe air extraction.

The hot gas and solid particles first pass through a high-pressure water curtain created by numerous precision nozzles. This dense mist acts as a barrier - and only our units provide such efficiency, as we have conducted thorough pressure and nozzle-position testing to achieve complete impermeability to combustion products.

All unwanted substances are then captured in the water, which is discharged into the drainage system once a day.

Meanwhile, the air continues its path towards secondary filtration.

Removable ceramic cassette filters trap fine particles and atomised grease that remain in the gas mixture. Why removable cassettes? Because they make maintenance quick and convenient. The ceramic filters can be easily taken out and cleaned as needed - we recommend once a month, though this depends on your production process.

Because our systems operate with very high water pressure, droplet separators are installed at the outlet. These prevent leaks into the ventilation ducts and provide additional filtration of the air mixture.

As a result, the outlet air is dry, of comfortable temperature, and with minimal traces of smoke.

For complete smoke removal, we recommend installing an electrostatic filter, which we also supply. And if total odour elimination is required at the ventilation outlet, we offer a professional industrial ozone air purifier designed specifically for kitchen odour removal.

Throughout the entire airflow path, service hatches are strategically placed for easy maintenance. The entire process is controlled by an electronic system based on readings from sensors and measuring instruments.

A key feature is the automatic self-cleaning function, which can operate even during equipment use - meaning the hydrofilter can be fully cleaned by the time the restaurant closes for the day.

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

We also cooperate with ventilation companies, providing comprehensive air purification and fire-safety solutions.
