Electrostatic Precipitator (ESP)
Filter Unit
Technical and Operations Manual - Product Overview 8
2.2 Features
The following features are applicable to all four models covered by this manual:
● They can be installed outside without an additional weather housing.
The Unit’s casings is fully weatherproofed, with the Main Door components having
an IP Rating of 64 and the Door Assemblies themselves being tightly sealed to the
main chassis.
● The ionisation voltage runs at a negative potential which enhances both the
ionisation of particles and their consequent precipitation and the production of ozone
which helps eliminate odours in a kitchen environment.
● A high degree of efficiency, with power consumption between 20 Watts and 50
Watts, depending on the model.
● The Unit can be linked to a Building Management System (BMS) via a suitable
relay mounted on the DIN rail (See:
Connecting the Unit to a Building Management
System on page 21
).
● All internal components are designed for easy removal.
● The Mesh Filters (Pre and Post) are designed to drain independently and the
Collector Cell is designed to be efficient, robust and effective.
● The Collector Cells and Filter Carriers can be easily removed for cleaning.
● The Collector Cells can be fitted with ionisation wires or with stainless steel spiked
ioniser blades.
● All internal surfaces are as smooth and as free from screw and rivet heads as
practically possible to allow for ease of cleaning.
● Fully welded sumps prevent leakage of collected grease. The inward sloping edges
of the sumps encourage the flow of grease away from both the ducting and either
side of the Unit.
● The Door Assemblies are designed to allow the Unit to be quickly reconfigured for
different airflow directions.
2.3 Operating Principles
Commercial kitchen exhaust pollution is composed of two distinct phases:
● The particulate phase; oil, smoke and grease particles.
● The gaseous or odour phase.
2.3.1 Oil, Smoke and Grease Filtration
The primary function of Purified Air’s range of Electrostatic Precipitators (ESPs) is to
effectively filter the particulate phase (oil, smoke and grease) of extracted kitchen fumes.
The Unit covered by this manual utilises an ionisation process to filter particulates in the
exhaust down to a sub-micron level, with an efficiency of up to 98% when fitted correctly.
The ESP Filters have been exclusively designed for filtering extracted kitchen fumes and
have integral sumps built in to collect the oil and grease particles. This not only simplifies
servicing but eradicates potentially dangerous spillage from the bottom of the Unit.
