Product Application

Aluminum partition application scenarios

Paper partition application scenarios

1.Strict environmental requirements

High temperature places: sterilization cabinet exhaust, oven air supply (>100℃), high temperature clean workshop.

High humidity environment: biological fermentation workshop, food processing area, tropical areas without constant humidity system.

Highly corrosive: chemical laboratory, electroplating workshop surrounding (aluminum corrosion resistance is better than ordinary paper).

Fire protection requirements: operating room, nuclear facilities, data center and other scenes where Class A non-combustible materials are mandatory.

2. Long-term reliable operation

Cannot be replaced frequently: production lines with complex installation locations (such as FFU top) and high downtime costs.

Key protection areas: BSL-3/4 laboratories, vaccine production lines, ICU wards (failure = major risk).

3. High return on investment scenario

Although the initial cost is high, the total cost over a 10-year life cycle may be lower than replacing paper partition filters twice + downtime losses.

1.Cost-sensitive projects

Cleanrooms with limited budgets (such as ordinary electronic assembly workshops and packaging areas).

Return air filtration in non-core areas (such as corridors and secondary filtration in locker rooms).

2.Dry and controlled environment

Cleanrooms with constant temperature and humidity (temperature 20-25℃, humidity 45%-65%).

Temporary clean facilities for short-term use (such as exhibition laboratories).

3.Lightweight requirements

Old factory renovation projects with limited ceiling load-bearing capacity.

Advantages of HEPA Deep Pleat Air Filter

High efficiency and low resistance: HEPA Deep Pleat Air Filter has extremely high capture efficiency for 0.3μm particles (H13: 99.95%, H14: 99.995%) while maintaining relatively low initial resistance.
Stable and reliable structure: The partition provides strong support to ensure that the filter material does not deform or collapse under the rated air volume or pressure difference, thereby maintaining the stability of performance and extending the service life.
Higher dust holding capacity: The stable structural design allows more dust to accumulate without causing rapid blockage or damage.
Uniform airflow distribution: The design of the partition helps to guide the airflow more evenly through the entire filter cross section, thereby making full use of the performance of the filter material.
Excellent weather resistance (especially aluminum partition): Aluminum partitions are resistant to high temperature, high humidity and corrosion, and have good fire resistance, suitable for harsh environmental conditions.
Wide range of applications: Suitable for most clean industries that require high-efficiency filtration.

Features of HEPA Deep Pleat Air Filter

The material is usually aluminum foil or paper partition, arranged in a zigzag or wavy shape, used to support the filter material and form a uniform airflow channel.

The filtration efficiency of 0.3μm particles is ≥99.97% (H13 grade). Glass fiber filter material is used to ensure low resistance and high efficiency. Deep pleated HEPA air handler filter achieves high air volume handling capacity by increasing the filter area (such as deep pleat design) and optimizing the partition spacing.

FAQ

Q: What are the advantages of high efficiency filters with partitions compared to high efficiency filters without partitions?

A: The structure of the partition model is more stable under high temperature (>150℃) and high resistance fluctuations, and the dust holding capacity is 30% higher, which is suitable for industrial clean rooms with long-term continuous operation; the high efficiency without partitions is more compact and suitable for medical scenarios with limited space (such as operating room ceilings).

Q: Is PAO leak detection required after installation?

A: Yes, PAO leak detection is a mandatory step. Filters that fail the leak detection (leakage rate>0.001%) will cause the number of particles in the clean room to exceed the standard, and the seals need to be reinstalled or replaced.

Q: Can it be used in the exhaust system?

A: Yes, but you need to choose the "negative pressure resistant type" (pressure difference ≥500Pa), and the joint between the frame and the filter material needs to be sealed to prevent the filter material from falling off due to negative pressure; the exhaust of the biosafety laboratory needs to be equipped with an activated carbon layer to adsorb organic gases.

Q: How much does the pre-filter affect its life?

A: The front end needs to be equipped with F8 medium efficiency and H11 sub-high efficiency filters in sequence, which can intercept more than 99% of 1μm particles and extend the high efficiency life of the partition to 2-3 years; if the sub-high efficiency filtration is omitted, the life will be shortened to 6-12 months, and the comprehensive cost will increase by 3 times.
