Product Introduction

Primary filters: the first line of defence in air purification

The primary filter is the ‘front guard’ of the air purification system, mainly used to intercept large particles above 5 microns in the air, such as dust, hair, fibres and pollen. As the first layer of a multi-stage filtration system, its core role is to protect the back-end high-efficiency filters (such as HEPA) from being clogged by large particles, thus extending the overall equipment life and reducing energy consumption.

In industrial workshops, commercial buildings and domestic air conditioning, the need for primary filters is reflected in three ways:

1. Economy

Filter 60%-80% of coarse particles, reduce the frequency of high-efficiency filter replacement, saving maintenance costs.

2. Efficiency guarantee

Prevent large particles from covering the pores on the surface of the high-efficiency filter, maintaining the stability of the system's airflow and purification efficiency.

3. Widely applicable

Washable or replaceable metal mesh, chemical fibre materials are suitable for scenes with high dust concentration (e.g. building ventilation, factory pre-treatment).

According to statistics, without the installation of primary filter purification equipment, high-efficiency filter element life shortened by more than 40% on average. Whether it is to protect precision instruments or to improve indoor air quality, primary filters have become an indispensable cornerstone of modern air management with their low-cost and cost-effective features.

Product Characteristics

Cheap, light weight, good versatility, reduce operating costs.

The outer frame is made of galvanised frame or aluminium frame, and the filter material is made of high-quality polyester synthetic fibre attached with rhombic mesh or welded wire mesh folded and shaped.

Compact structure, commonly used in the ventilation system of the first level of filtration.

It is also suitable for air-conditioning and ventilation system which only needs one level of filtration.

Filter efficiency:

G3 (EN779) / MERV6 (ASHRAE52.2) G4 (EN779) / MERV8 (ASHRAE52.2)

Applications

Pre-filtration of general air-conditioning and ventilation systems to avoid the accumulation of dust and pollution within the system.

Pre-filtration of large air compressor.

Centralized ventilation and air-conditioning systems and return air filtration in clean rooms to prolong the service life of high-efficiency filters at the back stage.

Pre-filtration of general industrial plant ventilation system to achieve general clean air requirements.

Frequently Asked Questions

Q1 What is the primary role of a primary air filter?

The primary air filter serves as the front guard of the air purification system, capturing coarse particles above 5 microns such as dust, pollen, fibres, and hair to protect subsequent high-efficiency filters from clogging.

Q2 How much can a primary filter extend the service life of HEPA filters?

Without installing a primary filter, high-efficiency filter element lifespan is shortened by over 40% on average. By capturing 60%–80% of coarse particles, it significantly extends backend filter life and reduces system operating costs.

Q3 What efficiency ratings are available for these filters?

These filters are available in standard efficiency ratings of G3 (EN779) / MERV6 (ASHRAE 52.2) and G4 (EN779) / MERV8 (ASHRAE 52.2).

Q4 What frame and media materials are used in construction?

The outer frame is constructed from either galvanised or aluminium frames, while the filtration media utilizes high-quality polyester synthetic fibre attached to a rhombic or welded wire mesh folded and shaped for maximum durability.

Q5 Where are these primary air filters commonly used?

They are widely applied in general HVAC pre-filtration, large air compressors, clean room return air systems, and general industrial plant ventilation setups.

Q6 Are custom dimensions available for specific ventilation units?

Yes, special sizes, non-standard dimensions, and unique specifications can be custom manufactured according to customer requirements.
