Candle Filter for Petroleum and Pharmacy Industries

Boegger candle filter, also called filter tube or filter cylinder is a common type filter strainer, the stainless steel woven wire mesh and perforated metal welded in tube, cylinder and pipe shape to separate gas and liquid. And different layer number, different mesh size and different diameter thickness are required to ensure high accurate filtration fineness. Candle filter with perforated metal mesh has high bending and crimping resistance, which can provide rigidity and durability in applications. And they are mainly used in petroleum, pharmacy, chemical, water treatment and foodstuff industries.

Five perforated stainless steel candle filters and a folding woven wire candle filter on the floor.

Perforated stainless steel candle filter has high tensile strength to resist high pressure and heat.

Stainless steel woven mesh filters are acid and alkali resistant, and they can help to stop the foreign particles.

Three sizes of candle filters, and they have perforated metal with round hole outside and stainless woven wire mesh inside.

Filter tubes which combine perforated metal and woven wire mesh together have better and stable filtration performance.

A folding woven wire mesh making an candle filter, and it has high mesh number for efficient filtration.

Candle filters made of folding woven wire mesh have high filter fineness and can efficiently filter gas out of liquid.

To ensure the accuracy, candle filters are always have multilayer to resist pressure and corrosion.


Boegger candle filters or filter pipes and tubes usually are made of multilayer sintered wire mesh and perforated metal, which are widely applied in the filtration of liquid and gas. They can combine adsorption and filtration together to remove the organic matter, radio-active substance and foreign particles from water and liquid. And they also can remove unpleasant taste and odors. Therefore our candle filters can be widely used in petroleum, chemical, heavy-duty, machine, pharmaceutical, environmental protection, food and beverage industries. To be applied for gas distribution, water treatment, dust removing, air purification, solid-liquid separation, gas-liquid separation, dry filtration and dustproof.
