Airtight provide expansion solution

Increased production requirements, ongoing machinery purchases and expanding factory space meant that Auckland based door manufacturer Sage Doors were running out of extraction capacity with their existing dust extraction system, so they added a second one and linked it to the existing set up to utilise valuable non-accessible space.

When buying their latest CNC machine last September, Sage Doors knew they were already near their extraction limits, they were also expanding their factory space and so the timing to look at upgrading their dust extraction was right.

“Our current system was an Airtight one which had been running trouble free and very efficiently for ten years, so it was always going to be Airtight Solutions we looked to first for advice on increasing our capacity,” says Michael Posthuma, speaking about his family’s business.

“While always important, price was not really a key element for us, we were happy to spend a little more if that was required to get the best. The cost and consequences are really spread over a long time, so it pays to get it right.”

“We spoke to Brett Borthwick from Airtight Solutions, and told him that due to space restrictions, we wanted a second extraction system in which the dust is transferred back to our existing system. Airtight suggested a tranfer fan to blow the dust to our existing hopper and bin at the front of the property.”

Once specified and formatted, installation of the four modular baghouse unit was relatively simple with Airtight installing the unit and Sage Doors running the ducting as they wanted it.

“The Airtight ducting system is I think the best available, its clip action makes for easy movement of machinery, something we have done many times over the years. It just unclips and reclips, making it very easy to install new machines or re-arrange factory layout. For this install most of the ducting was standard with just custom made branch pieces as required.”

The system is a positive pressure filter designed to evenly distribute the airflow and dust in the filter socks. Airtight’s reverse airflow cleaning automatically cleans the dust from the filter bags from where it’s transferred via the transfer fan to the front of the factory for easy removal.

“Airtight are very professional,” says Michael. “Brett is very knowledgeable, someone you can ask a question of and get a good answer from. He has returned a couple of time to check the pressure, but there is virtually no maintenance required, we will be right for the next 20 years.”
