Pressure filters


Taking into account the needs of each customer and the type of application, Salher designs customised pressure filters.

In order to manufacture in GFRP (fibreglass reinforced polyester), Salher also uses resins and fibres suitable for the requirements of chemical and mechanical resistance.

Type of filters

High Performance Vertical Industrial Filters

Type of filters

Large Capacity Horizontal Industrial Filters

Type of filters

Filters for limited height spaces (installations in cabinets, basements,…).

For all these types, Salher offers designs with diameters of up to 4 metres and of any height or length. All Salher filters are equipped with a manhole and a top cover with a ventilation system and an integrated pressure controller.


  • Drinking water,
  • Desalination,
  • Swimming pools,
  • Process water,
  • Wastewater,
  • Corrosive environments.


  1. Manhole sump, GFRP.
  2. Top cover with vent / pressure gauge.
  3. Drainage inlet.
  4. GFRP support base.
  5. Lifting lugs in AISI 304 stainless steel.
  6. External polyurethane paint (UV resistant).
  7. Battery of actuated valves.
  8. Filling of the filter according to the application.
  9. Distribution system by means of strainer plates / collector arms.
  10. Water and air cleaning.

The configuration of the filters can be adapted to the needs of each customer and the use made of them: number of filters, type and position of flanges and vents, sight glasses, control sensors, vents, etc.

Salher designs its filters taking into account:

  • the volume of the water inlet provided for in the installation,
  • the space available for the location of the equipment or
  • the application for which the filters will be used.

In this way, Salher has a wide range of models, which will be adapted in each case to cover all the water treatment requirements. For example, large horizontal filters for desalination plants, sand filters, carbon filters or descaling filters, among others.

Salher uses resins and fibres adapted to the requirements of chemical and thermal resistance: isophthalic, orthophthalic, vinylester, ultra-reinforced (U.R.), etc.

All Salher brand pressure equipment is distinguished by its quality and durability.

Do not hesitate to contact us: we will study your case and design the most suitable filter for your needs.
