Classic Filters News

Have you ever wondered what pushes the price of a CE marked filter housings with flanges up? You might be surprised to find out it’s the welding process. Read how our engineers managed to reduce production cost by removing this step.

The two key types of filters that our clients ask us about most are particulate and coalescing filtration systems. Let’s explain them for you here.

Here at Classic Filters we are constantly being asked to solve customers problems. Today we are going to look at two of the most common problems found in coalescing filtration and in the use of catch pots

We were recently asked to solve a problem for a customer with a problem of high levels of pipe rouge and rust particles in his sample. The application was on white product blending.

A common question that is often asked is:-

I have installed a coalescing filter but I’m still getting liquid out of the line at point of use, why?
First point is that the coalescing filter should be fitted as close to the point of use as is possible.

We have been looking after Classic Filters social media strategy and social media management since early 2011. As well as helping create this blog and plan the successful webinar series we have been trying to build up a network and engage with the Filtration Industry on social media.

What is a borosilicate glass microfiber element?

Borosilicate glass is known and used quite extensively throughout the glass industry, specifically for laboratory glassware, being made from Boron and Silica, and the microfibers are what they say they are, very fine fibre of specific diameters and lengths blended and formed in a specific manor to produce a matrix with certain sizes of free area dependant on grade.

One of the problems with a 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 after a coalescing filter

Analyser builders and system builders are often hit with a request 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.

Here at Classic Filters we have been asked to solve high pressure applications on several occasions. The most recent was for a filter housing with a maximum working pressure of 1050bar which the customer specified LF 6 connections.

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? Read why we don’t recommend a second support.

A packaging company recently came to us with a problem to do with their air operated process picking arms. At their packaging plant due to limited space and complicated routing of compressed air lines – which are notoriously wet and dirty – water was swamping the filters and travelling straight to the robotic process picking arms. No standard unit was going to do the job in these conditions so we had to come up with something new.

Following on from our blog in February about borosilicate glass microfibre filter elements, we are now looking at when you should use support cores with these filters and the advantages to using them. This particular post focusses on liquid filtration and coalescing and gives reasons and examples of when to use a support core with the element.

Fast Loop housings can be used to make the connection and filtering of the sample easy, they also reduce analyser response times. This blog explores where fast loop filters fit into the overall sample line and the advantages of using these filters in your samples.

A question that has arisen time and time again from our customers is do we manufacture Compressed Natural Gas (CNG) Filters and the simple answer is YES we do! and we have been doing so for many years. In fact we have a large number of products that can be used for Compressed natural gas, but over the years we have also designed some products specifically for this purpose.

Anyone who has seen filters in action will know it is not an uncommon sight to find filters fitted with a simple gauze filter element. But what happens when a mesh filter is just not enough?

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 what happens if a filter stops working before the next service visit?

Recently we had a customer who had installed a filter system in his sample system line. This system comprised of a coalescing filter followed by a particulate filter. The customer wanted to be certain that any liquid that built up in the system could not reach the analyser and flood the filter housing however he could not use glass due the pressure of the system.

Did you know that using a sintered filter element can actually cost you more money than you think? If you use these filters in your system because they can be cleaned and do not need replacing very often, you could be spending more money on your Energy bills than a Borosilicate Glass microfiber filter element would cost. Read our blog to find out why.

We have some great news, the very popular SS117 and SS127 our smallest internal volume 316L SS housings, are now built as standard to 350bar maximum working pressure.

From time to time we get asked to help our Distributors and their customers overcome a problem that they have struggled to overcome themselves. One of our distributors asked us to help by designing a new product to over come an air lock problem. This blog posts looks at how working within a Distributor Network allows for more joined up working and bespoke product development.

In today’s tough economic climate, all businesses are looking at ways to reduce overheads and increase the cash-flow of the business. One way a number of manufacturing firms are looking to do this is through the reclamation of precious metals. This is common in plating processes but we are also seeing other manufacturing companies using filters to reclaim metals from liquid suspensions. Read our blog to see how we can provide the right filter for your reclamation process.

Classic Filters is pleased to welcome Monitoring Ventil and Fitting have been appointed as our exclusive distributor for Russia, Belarus and Kazakhstan. This will help to strengthen our position as a worldwide supplier of filters, filter housings and complete filter systems for a variety of different functions.
