The industry standard for commercial kitchen air filtration

Electrostatic Precipitators (ESPs) are inline air filtration systems designed specifically for commercial kitchen extract systems. Installed directly in the extract ductwork, they capture grease-laden vapour, smoke, and airborne particulates generated during cooking, before they reach the atmosphere or accumulate in the duct. Using high-voltage electrostatic charging and collection plates, our ESP range filters particles down to sub-micron levels (0.01 microns) at up to 98% efficiency, protecting building fabric, reducing fire risk, ensuring odor compliance, and meeting the requirements of NFPA 96.

The benefits of electrostatic technology

•Eliminates up to 98% of particles
•Filters particles down to sub-micron levels (0.01 microns)
•Modular design, scalable from single units to large turnkey installations
•Low power consumption, energy efficient operation

ESP units must be interlocked with the extract fan. Units are modular, multiple ESPs can be combined to handle any extract volume requirement.

Clean exhaust airflow

Our ESP units fit in-line with the kitchen ducting and can be configured modularly to cope with all extract volume requirements.

ESP systems support compliance with NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) by reducing grease accumulation in ductwork, one of the primary fire risk factors in commercial kitchen ventilation. Our team can advise on system sizing and positioning to meet your local authority and insurance requirements.
