How can you use a disposable in-line filter to save space? One of our OEM customers uses NN112.201 filter housings for particulate removal in their portable flue gas analysers. These housings offer a low cost, high efficiency solution for stack gas applications and are widely specified. However, for a new gas analyser they found that…
We are happy to announce that one of the products we have been asked for on a number of occasions, a PTFE-membrane housing for aggressive or demanding environments, is now part of our continued product list. We do manufacture the standard SM106 and SM125 housing in PTFE but in most cases the customer just wants…
We have some great news. The very popular SS117 and SS127 series, our smallest internal volume 316L stainless steel filter housings, are now built as standard to 350 bar maximum working pressure. We know that most applications don’t require anywhere near this kind of pressure, but because we have been asked quite regularly for process…
Recently we had a customer who had installed a filter system in his sample system to protect an online analyser. This sample system comprised of a coalescing filter followed by a finer particulate filter. The customer wanted to be certain that any liquid being removed by the coalescing filter was draining away from the housing…
Does your application need a differential pressure indicator? Recently we were asked to solve a problem for a company operating unmanned oil production platforms. The way these platforms work mean that all of the systems are monitored remotely. Unless something out of the ordinary happens no-one visits the platforms until the regular service visit. However, one…
Fast Loop housings can be used in sample systems to transport the sample closer to the analyser at high speed to reduce analyser response times. Where do Fast Loop Filters fit? The housing fits into the fast loop or bypass line wand has a direct flow straight through the fast loop housing and through the…
A question that has been asked a lot is when using a membrane as a filter to stop moisture passing, should the membrane be supported on one side or on both? The first thing to look at is the membrane itself. What is a membrane filter? The membrane is a very thin film of hydrophobic PTFE which means…
Analyser manufacturers and system builders are often equested to have the filters accessible for ease of element change. The problems that are faced can include a complication in the systems where the element needs to be changed after each test or where shut down time has to be kept to a minimum. How We Make…
Do you need a Liquid Block option? One of the problems with a PTFE membrane is if it sees too much water, it will eventually breach and allow moisture through to the analyser or piece of equipment being protected. For this reason we always suggest that the membrane only be used as a police filter…
We were recently asked to solve a problem for a customer who saw high levels of pipe rouge and rust particles in his sample. The application was on white product blending. So What What Was The Problem? Unusually the problem was not so much to do with the filtration but with the stainless steel filter…
We recently had an unusual application for our filter solutions in the food industry – cleaning salad! When salad arrives to be packed it is in a wash of chlorine, this is mostly to stop the growth of mould but also to kill bacteria and insects.Before the salad can be packed for the supermarket shelf,…
One of our OEM customers successfully uses the SML206.221.M8 PTFE Membrane Housing to remove water from a diesel sample system prior to an on-line analyser. Recently a new application required a larger flow rate at lower pressure so we designed a new sized housing for them. The SML304 series uses a larger 89mm diameter PTFE…
