Small Enough
to Care

David started making wire frame filters with Don Carley at Southern Filters in Redhill, Surrey in May 1985, and went on to buy the company from Don in 1989.

He worked on his own until the early 1990s, when he found he could not single-handedly keep up with production, so began to take on staff.  The company has since then grown steadily, to our current staff level of 25.  We currently manufacture over 19000 different items, across seven departments.

David relocated the company from Redhill to Shaftesbury in 1999 when we moved to our first new, purpose-built industrial unit.

We remain a small, friendly team, nice people to do business with – and now occupy four units with over 11,000 square feet of manufacturing space, and continue to look for more space!

Meet our Team

We manufacture from our Shaftesbury factory with a team of 25 staff.

A happy working atmosphere is important to us, as is our training of staff.   Many employees have transferable skills across the factory, so we can direct our efforts towards the most urgent departments. We are proud of our very low staff turnover – many have been with us for about a decade.

Everyone works hard to ensure your order is manufactured to specification, on time and delivered to its destination.  We make daily despatches with a range of trusted carriers.
