World Class Filtration Solutions
Porvair Filtration Group has supplied a comprehensive range of filtration and separation products to the energy market since the 1980s. Our technology is used throughout a wide range of applications. These include, but are not limited to, clean coal technologies, gasification and alternative energy technologies. Our unrivalled experience and extensive product range ensures that we can supply a fully engineered tailored solution for every application in accordance with industry standards.
Porvair Filtration Group has the capability to provide a range of products from a single, specialised, retrofit element to complete fabrications, packages and vessels to meet the precise needs of a complex application. This is complimented by on-site support and a complete after sales service. In addition to our acknowledged leadership in both engineering and quality, we also have the capability to offer the services of our extensive laboratory, development and testing facilities.
We are also active in a number of areas concerning the generation and safeguarding of energy production, and are leading innovations in gasification technologies to enable the production of synthetic natural gas (syngas or biogas) as part of alternative clean energy techniques, minimising the cost of ownership and ensuring the availability of clean dry gas. We are also using our expertise in filtration technology in a variety of alternative energy projects where our high performance media is a pre-requisite for emerging and developing technologies.
We design, engineer and manufacture high performance filters with apertures sizes, ranging from 100's microns to sub-micronic pore structures using sintered composite mesh, sintered metal fibre and sintered powder media structures in cylindrical element and pleated filter cartridge formats as well as specialist bespoke designs.
We manufacture metallic and polymeric filter media in both cartridge and element forms, with a variety of end hardware to suit any housing or vessel configuration.
Sinterflo® sintered porous metal materials are ideal for applications that involve aggressive chemical environments, high temperatures and high pressures.
Both mechanically and chemically robust, these materials allow for effective cleaning for reuse thereby delivering cost-effective solutions for difficult applications, reducing the long term cost of ownership through operating life longevisity and increased onstream/campaign life. The range of Sinterflo® sintered porous metal materials includes:
Porvair Filtration Group also provides design and engineering services for pressure vessels and other containments custom designed specifically for the filter elements and cartridges supplied.
Porvair has developed Porvair Sinterguard® surface modification procedures through a series of patented CVD processes to significantly enhance both oxidation and sulphidation resistance in instances where the operating conditions demand it.
We have also developed patented technology to modify the surface chemistry and physical properties of our metallic filter media to improve its performance in the harshest extremes of temperature, pressure and corrosive environments. Our Porvair Sinterguard® technology is proven to improve filter lifetime and reduce overall life cycle costs of operation.
The Porvair Pulsejet cleaning process was developed by Porvair Filtration Group over 30 years ago and is for the effective removal of collected solids from the surface of a filter element or cartridge.
The process is typically undertaken whilst the filter is in operation on-line and, apart from a very small pressure spike (or ‘overpressure'), it does not interrupt or interfere with the process flow.
Pulsejet filters allows a properly designed system to reach a stable operating pressure differential in the long term, returning to the user nearly all the solids collected for effective, minimum volume disposal or re-use.
The technique and its associated equipment can be designed to be used in high temperature, high solids, high pressure, chemically aggressive and highly active environments to provide filtration down to very fine levels, with continuous operation and consistent/controlled differential pressure loss/rise, allowing the accurate specification of complementary equipment around the filter.
