In the HVAC and ventilation sector, the variety of catalog products is far greater than in any other filter industry segment: a manufacturer serving the building market might handle G3/G4 pre-filters for commercial air handling units, M5-F7 panels for industrial systems, F8/F9 rigid pocket filters for hospitals and data centers, and HEPA filters for critical environments like operating rooms and cleanrooms. SPM covers this entire range using a single technology platform, as the differences between these products lie in the filter media and process parameters rather than the machine’s fundamental construction logic.
The most common operational challenge for HVAC manufacturers is not production speed—throughput rates in this sector are rarely the bottleneck—but rather managing a multitude of product codes on a single line. An HVAC catalog can feature dozens of combinations regarding efficiency, panel dimensions, and separator types, with every variation requiring a setup change. SPM lines are configured for rapid format changes: widths from 150 to 1200 mm, pleat pitches from 5 to 30 mm, and heights from 0 to 300 mm (using the 91XFPC roller pleater for taller formats), with setup times that, in most cases, do not require maintenance intervention.
A frequently overlooked aspect of high-volume HVAC production is the coil changeover.
On a continuous production line, every depleted roll halts output—typically resulting in 15 minutes of downtime per hour, which amounts to nearly two hours of lost capacity over an eight-hour shift. The automatic splicing system developed by SPM absorbs this downtime into the production cycle without stopping the machine, yielding an estimated 15% increase in continuous productivity per shift—a figure that, given high volumes, quickly translates into additional production capacity without the need to invest in a second line. The same configuration flexibility that characterizes HVAC lines also applies to cell panels with hot-melt or aluminum separators, rigid pocket filters featuring minipleat media packs and epoxy bonding, and minipleat HEPA modules. A single SPM line—with the appropriate configuration parameters—can cover the entire product range offered in an HVAC manufacturer’s catalog.
