Product structure

1. Stainless Steel End Caps.
High-quality stainless steel end caps provide excellent corrosion resistance and reliable connection strength.

2. 304 Perforated Plate Inner Support
The inner perforated tube enhances structural stability and prevents the filter media from collapsing under airflow pressure.

3. Three Ear Flange
The three ear flange provides a secure connection between the filter element and the filtration equipment. Its practical design allows convenient installation, removal and routine filter replacement.

4. Filter Media
The main filtration layer is selected according to the application requirements. It captures dust, particles and other airborne impurities while providing stable filtration performance and suitable airflow.

5. Sealing Part
The sealing component helps create a proper seal between the filter element and housing, reducing the risk of unfiltered air bypassing the filtration media and supporting reliable filtration performance.

FAQ

 

Q1: How should I choose the correct filtration rating?
The required filtration rating depends on the particle size, required filtration efficiency, airflow and operating conditions. We can recommend a suitable specification based on your application.
 

Q2: Can the filter media be customized?
Yes. Polyester fiber, fiberglass, composite media and other suitable filter materials can be selected according to the application requirements.
 

Q3: Will the filter affect the airflow of my equipment?
Filter media, filtration rating and effective filtration area all influence airflow and pressure drop. We can select the filter structure according to the required airflow and equipment conditions.
 

Q4: How often should the air filter be replaced?
Service life depends on dust concentration, operating hours, airflow and pressure drop. In practice, replacement is generally recommended when pressure drop becomes excessive or filtration performance decreases.
 

Q5: Can you produce a sample before bulk production?
Yes. Samples can be produced for dimensional and installation verification before mass production.
 

Q6: What if I do not know the complete specifications of my original filter? 
You can provide the original filter, product photos, dimensions, equipment model or connection details. We can help identify the main specifications and develop a suitable replacement.
