Needle punched felt bags are a common filtering material commonly used in fields such as dust removal and filtration.
There are many types of needle punched felt bags, and the following are some common types of needle punched felt bags:
Ordinary polyester needle punched felt bag: suitable for filtering general dust, with a working temperature generally below 130 ℃.
Acrylic needle punched felt filter bag: suitable for high filtration temperature conditions, with a working temperature of up to 160 ℃.
PPS needle punched felt bag: suitable for filtration in high temperature and acid-base environments, with a working temperature generally around 190 ℃.
PTFE needle punched felt bag: suitable for filtration in high temperature and corrosive environments, with a working temperature of up to 260 ℃.
Glass fiber needle punched felt bag: suitable for filtering corrosive gases and dust in high temperature and humidity environments, with a working temperature of up to 260 ℃.
Metal fiber needle punched felt bag: suitable for filtering high-temperature and corrosive gases, with a working temperature of over 1000 ℃.
It is necessary to select suitable materials and models of needle felt filter bags based on specific operating conditions and filtration requirements to achieve better filtration effect and service life.
