EFC is a proud partner and exclusive distributor for Springfield Spring Air Filter Clips.
The prevalence of air borne pathogens associated with the global COVID-19 Pandemic has spawned a host of Federal and Local indoor air quality filtration regulations in both commercial and residential buildings. Many of these new air quality building regulations are putting an unprecedented demand on the Air Filter Industry to engineer primary and secondary air filtration solutions which must meet higher MERV ratings. Many of these new air filters require specialized air filter holding clips.
A manufacturer of specialized Industrial and Commercial Air purification equipment approached Springfield Spring to help them develop a special fastening solution for various HEPA Filters used in their units. The challenge required Springfield Spring to engineer a fastener that could attach to the inside frame of their units with a feature to securely hold the HEPA Filters in place. The clip design required the clip to be easily adjusted for various filter sizes but also required easy hand manipulation to remove the air filters for maintenance and replacement.
The key to finding solutions for any customer’s problems begins with listening. After numerous Zoom meetings with their customer to determine the form, fit & function intent of the filter holding clip, they designed a smaller version of the standard 12” long filter clip. This smaller extension spring has a finger-pull handle feature with an integral mounting bracket. The spring required a flat surface along one plane of the clip with a specific spring force or “rate.” The integral bracket on one end of the clip required a small modification to its opening to fit on to the sheet metal frame of the customer’s unit. Samples were sent for qualification The following feedback from the customer affirmed the success of Springfield’s engagement and the final product.
“This special mini extension spring and bracket works exceptionally well in our Airbox Purification units. Your service from the day we reached out to you, to the submission of samples, was just incredible. Please express our sincere thanks and gratitude to your entire Engineering team for a job well done.”
