Stainless Steel Access Doors for Clean Rooms

This was kind of cool.  A.J. Manufacturing’s Stainless Steel Access Doors are used in the University of Illinois’ lab chamber, for swine research.  As you might imagine, everything is in an environmentally controlled clean room.  Our customer Karl Arend – Project Manager at Art’s-Way Scientific said  “They look great! Thank you for all your help. Thought you might want to see them in action.”

With support from several of our key material, component, and processing suppliers, A.J. was honored with the opportunity to share its story of innovation, mass customization, and one piece flow with industry peers and potential customers.  The broad range of products we design and manufacture for the various markets we serve, all expect best in class performance, product durability, and top-rated customer service.  Meeting these expectations is possible when the quality of the culture provides the necessary quality of foundation to support the effects of the organization being continuously pushed and pulled.

It is nearly impossible to describe the dynamic nature of how AJ has developed into a manufacturer that produces some of the highest performing products in various markets without spending a few days touring the four facilities, but the article appropriately focused on the common thread – our employees.  Quality training, an environment that promotes skill building and communication coupled with opportunity is the key to our continued growth.  The flexibility the organization has nurtured and allowed for diversification of products, services and markets served.    We hope you enjoy a glimpse into what we do and how we do it and we invite suppliers and customers who share our values, culture, and performance expectations to contact us.

New High Performance Gasket for Access Doors

I am pleased to announce an improvement to our product offering.  In a display of our commitment to continuous improvement and ever exceeding the needs of our customers, we have developed, tested and finalized a new high-performance gasket for our HVAC doors

18 months of development and testing have produced a gasket that will exceed your highest expectations. 

  • Just .25 cfm total air leakage at 10” wg. 
  • Not a drop of water over the sill after 15 minutes at -2”, -8”, and 14”, and 4 hours at -20”.
  • Extruded foamed EPDM rubber resists compression set, and maintains greater flexibility in cold temperatures
  • Field replaceable!   

The complete tests are available for your review.  [24×60 door tested in accordance with ASTM E-331] Thermal Door or Non-Thermal Door

We are implementing this improvement as a running change for all 2.0” aluminum frame doors.   You may have noticed that this improved gasket is already being used on all of our 1.7” doors.

Improved efficiencies in our processes here at AJ will allow us to upgrade sealing performance on all doors at no additional cost to you!

HVAC Access Door Gasket Performance: The Best Is About to Get Even Better!

The hvac access door gasket for AJ’s very first access door back in the year 2000 was fantastic for its time: independently tested by Architectural Testing Inc, it achieved virtually zero total air leakage at pressures as high as 10” w.g. for an outswing door under positive pressure.  No other manufacturer’s door came close.

Water leakage at the time wasn’t quite the issue it is today, but as performance expectations rose, our zero-leakage for 15 minutes at –3” w.g. was soon unacceptable.

In 2002 we introduced the foamed TPE gasket that you are familiar with, and when we combined that with our cakepan door panel design in 2005, water performance shot up to zero leakage at –7” w.g…again, best in the industry.

Today, after 18 months in development and 1 year in laboratory testing and field service, we announce the next stage in gasket design…our hollow-core EPDM gasket.

EPDM – a flexible sponge rubber – is widely used in the automotive and HVAC industries for door and light seals, and general weather stripping.  EPDM is valued for low-temperature flexibility, and excellent resistance to compression set, atmospheric degradation, alkalis, acids, and oxygenated solvents.

And our unique design allows continuous, 1-piece application to the frame.  No more corner joints.

That all sounds good, but does this new AJ gasket design seal any better?   You bet it does: ATI tested our non-thermal 24×60 cakepan door to the ASTM E331 protocol and reported zero leakage at pressures from –1” to –20” w.g.!

We are pleased to report that this new gasket will be phased into production in the very near future, beginning with our 1.7” door models.

Company Culture – The Foundation of Value

I am honored to admit spending the better part of my youth and young adult life on the “dumb-end” of a tape measure developing my construction and leadership skills especially when i was a carpet cleaner Penarth. My father was a Journeyman Carpenter in top travel system reviews, Job-site Superintendent, Project Manager, and ultimately Partner in Successful General Contracting firm. Just as his experience was built on the proper foundation of an apprenticeship and many years of skill development, a quality project is subject to the quality of the foundation. As your vendor/partner, we not only develop the quality of our materials, designs, and processes, we focus on the quality of our Company Culture – the foundation of our business.

What does a solid foundation look like at AJ? First of all it is wide at the base, we include every single employee in the process by communicating, skill building, and providing the proper tools to be successful. Second, we replace or shore-up weak areas with technology, equipment, process improvement and training. As with any foundation, it is subject to wear and tear and must be maintained. Third, as we work on our foundation, we remain focused on the plan, we are consistent in the execution of the steps necessary to meet the expectations of quality and growth we have established. Last but not least, we are open about the process, the dirty details, the issues that are holding us back and we ask for advice and assistance from experts when needed.

The next time you compare our forklift train the trainer and products against a competitive offering, and the basic cost and performance are similar – ask one more specification question – What is the culture of the vendor?

As my father says…..”If you don’t have the time to do it right the first time, where will you find the time to do it over?”

Build your business and reputation on a solid foundation, by focusing on the Culture.
