TAMPA, Florida — Stan Weaver & Company is proud to announce a significant product update from valued manufacturer partner, Greenheck. The KSQ, RSQ, and SQ Outdoor mixed flow wheel products have officially received Miami-Dade Notice of Acceptance (NOA) and Florida Product Approval (FPA), confirming their performance in high-wind conditions and expanding their use in hurricane-prone regions.
These certifications enhance the reliability and safety of these products in critical applications and represent a major leap in performance. The wind load ratings for these products are as high as ±90 psf for sizes 7 through 24, with strong performance continuing through sizes 27 to 33. These updates represent up to 2.25 times greater pressure resistance compared to previous models and are up to 20 psf higher than comparable competitor products.
Each product also brings distinct functional advantages:
- Greenheck KSQ: This award-winning, untempered, filtered rooftop supply fan is ideal for kitchen make-up air applications. All sizes ship fully assembled, streamlining installation and saving time on the job site.
- Greenheck RSQ: A fabra hood-style power roof ventilator designed for high-performance environments. Its new design eliminates internal support structures and excess fasteners, making installation easier while maintaining structural strength.
- Greenheck SQ Outdoor: The commercial inline SQ, when specified for outdoor use, now carries a wind load rating of 90 psf, making it a standout in the marketplace.
Greenheck is currently updating CAPS and marketing materials to reflect these changes. In the meantime, the team is ready to support customers with product selection and project guidance.
