482˚F (250˚C) high temperature HEPA filter manufacturer in China

The 250˚C high-temperature Heat resistant Hot Oven air filter is assembled with a glass fiber aluminum foil separator, stainless steel 304, 201, 316L frame, and special high-temperature silicone sealant. The two sides of the filter material are folded 180° to form a wedge-shaped pleated layer.

  • Can be equipped with a single or double-side metal mesh to protect filter media from damage.
  • Can be designed with a single or double header, DTF, and Box frame construction.
  • Can be designed to withstand 100% humidity application.
  • 100% tested to make sure no leakage and the correct dimension.
  • Customized sizes are available.

Features & Advantageous

  1. The unique frame design of the 1.5-2.00mm stainless steel outer frame increases the overall strength.
  2. The 0.03mm aluminum foil separator with circular arc corrugated grooves can not only protect the filter paper from damage but also reduce the resistance and the wind speed to pass evenly.
  3. The high-quality glass fiber filter paper has a spacing of 4mm, which increases the filter area and has a large dust holding capacity and small resistance and high filtration efficiency.
  4. The red silicone adhesive can be used for a long time at a MAX 250 degrees high temperature, and the temperature-resistant sealing strip ( Silicone bar ) is pasted on the air outlet side to prevent leakage.

Efficiency performance

  1. The filter material of high qualified glassfiber is selected, and the filtration efficiency can reach F9-H14.
  2. Ensure that the high efficiency level can reach 99.99%@0.3um under the rated air volume.
  3. It can be used in a high temperature environment of 250°C.
  4. Under the minimum resistance, the filter material can be used to the maximum airflow rate.
  5. Provide a variety of frame materials and thickness requirements.

250˚C Air filter for high-temperature powder curing oven

the 250˚C Air filter offers high-temperature heat resistance, high air purification efficiency H13 99.97% dust removal, and a cleanliness level of 100 ability. it is a replacement air filter for the powder curing oven.

It is made of stainless steel frame, glass fiber and high temperature resistant red silicone air seal solution. the filter provides a very good airflow rate and dust-holding ability.

All the construction materials can withstand a MAX 250˚C temp. 80% or 100% humidity. the stainless steel housing make sure air filter keeps stable in high temp and high airflow situation. to meet the requirement of different sizes of powder curing oven, we can offer a wide range of sizes, and customized sizes is welcome.

the filter media is separated by a corrugated aluminum foil, the side of the foil is double folded to prevent glassfiber media from damaged because of a sharp edge. Single or double side metal mesh to pretect filter media is available.


  • Glassfiber media
  • Stainless steel 201, 304, 316L frame
  • Metal mesh grille available
  • Class 100 cleanliness
  • H13 / H14/ U15 Efficiency available

Silicone-free design

We also offer a silicone-free high-temperature HEPA filter for some special Paint Curing Booth Drying Oven, which sometimes the silicone material will damage the process. Also for some industries such as semi-conductor.

the Ultra Clean Oven needs a HEPA filter to remove dust, our High-temperature design filters can withstand an extremely 250 to 400 centigrade. the filter made of superfine glass fiber can remove most of the micron-0.3 dust.

the stainless steel #201 #304 #316L frame can keep good stability in high-temperature conditions. A specially designed silicone or ceramic glue keeps good airtight and prevents any possibility of leakage.

the Oven HEPA filter is made of an aluminum foil separator, the perfect ability for bearing high temp and high humidity, strong acid, strong alkali.

This kind of filter is especially for some industries such as pharma high-temperature sterilizers, ultra-sonic, high-temperature spray, special chemicals and so on.
