Grease separators
What do grease separators in the kitchen affect
Grease separators are part of the basic equipment of every professional kitchen - they affect safety, hygiene, and costs
High separation efficiency
ATREA lamella and cyclone separators are designed for the most common sizes of grease aerosol particles. Therefore, only a minimum of grease ends up in the ductwork.
Safer operation
Less accumulated grease in the hood and ductwork means a lower probability of ignition and fire spreading through the ventilation system. Separators are an important part of fire protection.
Hygiene and comfort in the kitchen
Grease separation efficiency limits surface contamination and the formation of greasy film. The kitchen environment is cleaner, with less odor and more pleasant working conditions for staff.
Easy maintenance and long service life
Separators made of high-quality materials are washable and reusable. With proper design and regular cleaning, they operate reliably and long-term for many years.
PROVEN SOLUTION
Lamella grease separators
Lamella separators change the airflow direction several times. Due to inertia, grease aerosols impact the surface of the lamellas, condense, and flow down into collection channels. As a result, air with a significantly reduced grease content enters the exhaust duct, while separated aerosols are safely removed from the airflow.
Main advantages of lamella separators
- a proven standard with long-term verified performance,
- high separation efficiency at recommended airflow rates and reasonable pressure loss,
- easily removable, washable, and reusable,
- resistant to high temperatures and demanding kitchen environments.
PROVEN SOLUTION
Cyclone grease aerosol separators
Cyclone separators create a rotational airflow inside the chamber – a cyclone. Grease particles are carried by centrifugal force to the walls of the separator, where they condense and are removed as separated aerosols. As a result, air with a minimal content of fine grease particles enters the exhaust duct, which would otherwise cause significant fouling of ductwork and fans.
Main advantages of cyclone separators
- very high efficiency in separating fine grease aerosols,
- significantly longer intervals between cleaning of ventilation ductwork,
- stable operation even under high load and long operating hours,
- robust design with long service life in demanding environments.
SAFE OPERATION
Safety, hygiene, and operating costs
Grease accumulated in the hood and ductwork acts as a fuel that accelerates fire spread in the event of ignition. High-quality grease separators therefore significantly contribute to meeting fire safety and hygiene requirements, as well as insurance conditions.
Effective grease separation also
- reduces the frequency and cost of duct cleaning,
- reduces load on fans and extends their service life,
- helps maintain stable ventilation system performance throughout the entire operating period.
As a result, grease separators are not a weak point of the system, but its strength – they increase safety and reduce operating costs in the long term.
PART OF THE SYSTEM
Integration of separators with ATREA products
Both lamella and cyclone separators are not standalone devices but an integrated part of ATREA products. Together, they form a single interconnected system – from grease capture directly above the cooking surface to the safe extraction of air.
- Lamella grease separators – standard equipment of ATREA kitchen hoods, suitable for most common and medium-load catering operations.
- Cyclone grease aerosol separators – integrated into ATREA ventilation ceilings, designed for large and demanding kitchens with high operating intensity.
- Both types of separators work in conjunction with ATREA kitchen ventilation units, which are designed for operation with grease-laden air.
REFERENCE FROM OPERATION
Hotel kitchen with lamella filters
In a hotel restaurant with all-day operation, the original hoods were replaced with an ATREA solution featuring integrated lamella grease separators. After commissioning, duct contamination and cleaning frequency were significantly reduced. Staff appreciated a cleaner environment with less noticeable odor, and the operator benefited from lower maintenance costs. The system also met stricter insurance requirements for kitchen fire safety.
LARGE-SCALE KITCHEN IN PRACTICE
Central kitchen with cyclone separators
In a central kitchen serving multiple food service operations, an ATREA ventilation ceiling with cyclone grease aerosol separators was installed. The solution handles high-intensity cooking in an almost continuous operating mode, significantly reduces duct contamination, and extends intervals between necessary cleaning. As a result, the operator obtained a stable and safe system capable of handling peak loads without restricting operation.
Grease separators comply with the strictest European standards
ATREA grease separators have undergone rigorous testing in a leading European laboratory, DMT. They meet the standards required for kitchen operations, such as the German VDI 2052 certification, EN 16282, and DIN 18869-5. They ensure safe and efficient operation.
