The Andreae HE Original Filter will bring a filtration efficiency near 100% while keeping the high loading capacity of the Andreae Original filter. The HE is made out of 2 layers of heavy “kraft” paper, punched, pleated and glued together completed with a polyester layer on its back increasing its filtration efficiency.

Features:

• Low air velocity resistance
• Economical
• High Dust holding capacity
• Washable

Application: Pre-filtration for commercial and industrial ventilation systems and air conditioning systems.

1. Used for clean room conditioning system, pre-filtration through fresh air venting units, and exterior air 

conditioning connection.

2. Primary filtration of central air conditioning system.

3. Pre-filtration at the inlet of Air purification equipment.

4. Pre-filtration in a medium filter.

5. Primary filtration or secondary filtration in a filter system.

Features:

Sturdy structure and durable and long-lasting

washable material is available for your option, the filter can be repeatedly used after being flushed.

An optional detachable design allows for the reused of the outer frame and keel rack.

FILTRATION EFFICIENCY AND SERVICE LIFE

The raccoglivernice© (paint collectors) separate, from the exhaust air of

painting booths, the solid part of the overspray. The features of this type

of aerosol change in function of many parameters like:

• Painting product’s features

• Quantity sprayed

• Spraying technic

• Flow rate

• Transfer efficiency

The average efficiency and the service life are function of the following

parameters:

• Aerosol’s features

• Air velocity

• Distance between gun and filter

• Maximum allowed pressure drop

Therefore the performances of the product described in this technical

schedule vary and are typic of each individual installation. The true

performance have to be mesared “in situ”.

The Andreae HE Original Filter will bring a filtration efficiency near 100% while keeping the high loading capacity of the Andreae Original filter. The HE is made with 2 layers of heavy “kraft” paper, punched, pleated and glued together

completed with a polyester layer on its back increasing its filtration efficiency.

the Andreae has been the reference filter on the market. It remains the most universal and common filter in use. Our Original is made with 2 layers of heavy “kraft” paper, punched, pleated and glued together with 2 built-in extension limiters. Thanks to these limiters, the maximum load capacity is guaranteed. The Original is the filter for all paint types.

Feature:

- Simple and unique structure for easy installation.

- Economical pre-filter that can be reused after cleaning.

- Multiple pocket design for high air flow capacity.

- Optional detachable structure with reusable frame and keel rack.

Application: pre-filter and foreign material filtration in commercial and industrial ventilation systems

• Used for clean room conditioning system, pre-filtration through fresh air venting units, and exterior air conditioning connection
• Primary filtration of central air conditioning system
• Pre-filtration at the intake of Air purification equipment
• Pre-filtration in a medium filter
• Primary filtration or secondary filtration in a filter system

Hot melt bag filters usually use a bag structure to ensure that the air flow is evenly distributed throughout the bag. The design includes multiple layers of filter materials, such as coarse fiber filter cotton, fine fiber filter paper, and a protective layer, to achieve step-by-step filtration and improve filtration accuracy and service life. In addition, the design of the bag support grille prevents the bag from shrinking or bending out of shape in harsh environments, further enhancing the reliability of the device

Features:- 

High air tightness;ow resistance;High filtration performance and dust holding capacity;Long lasting;High air volume;The filter bag has high strength and is difficult to break or fall off;Silicon-free design.

Application

The hot melt bag filter has a high filtration efficiency, such as the removal efficiency of ≥1.0μm particles can reach more than 80%.

It is suitable for a variety of environments, including wet, high airflow and dust loads, and is widely used in pharmaceutical, automotive, food manufacturing, commercial buildings, and industrial ventilation systems
