Working Together

We have decades of experience and strive to be called upon for our expertise as well as for being a low cost producer. We know that only supplying less expensive filters is not all that is required to reduce overall filtration costs. We work with all our customers to explore the cost benefits and improved performance available with alternative solutions from new filter to process re-engineering – and can help implement new filtration systems and protocols.

Benchmarking for Improved Performance

Benchmarking is the most effective method of working together to improve filtration processes and reduce costs. Critical Process Filtration engineers can "Benchmark" your existing processes and determine whether significant improvements are feasible. This unique, no risk evaluation helps the customer to quantify the overall value of a process change. Should you determine that the recommended process change offers significant benefits, Critical Process Filtration engineers can provide products and services that ensure that you obtain those benefits.

Request Testing

Before implementing significant changes in filtration systems, you may want to have tests performed on your fluid, perhaps have tests conducted on used filters and, of course, test our filters in your process.

Setting up a test is simple. All you need to do click the link below to access our request form. The form should take only a few minutes to complete. We only ask for some basic information. A representative will contact you within one business day to ask a few more detailed questions and, if applicable, give some detailed instructions for handing samples and sending them to Critical Process Filtration. We turn around test results as soon as we are able, usually within a week of receiving the samples. If we are not able to complete the testing before then, we will give you an estimated completion date.
