The document discusses HVAC pre-filtration systems, which first eliminate large particles through pre-filtration before forced air circulation removes smaller particles. There are three main types of HVAC pre-filters: pocket filters, disposable pleated filters, and disposable panel filters. HVAC pre-filters are designed to have low pressure drops during pre-filtration, can handle filtration pressures up to 800 kPa, and remove dust particles ranging from millimeters to microns in size.

1. PRESENTATION ON HVAC-PRE
FILTRATION

2. ABOUT…
HVAC is termed as heating , ventilation and air
conditioning.
This system is equipped with the pre filtration system.
So firstly pre filtration process is done firstly due to
which the big particles are eliminated and remaining
small particles are gone by the forced blower air.

3. ITS TYPES..
The HVAC pre filter is three types for there application
point of view…
Pocket filter
Disposable pleated filter
Disposable panel filter

4. HVAC PRE FILTER

5. TECHNICAL SPECIFICATION…
It works in low pressure drop in the pre filtration
process.
The filtration pressure is about to 0 to 800 k pa.
Dust removing capacity in the range of mm to micron.
