The product portfolio spans 11 categories: fans, residential and non-residential ventilation systems, air diffusers and volume controllers, fire protection, ductwork, acoustic and thermal insulation, installation and maintenance hardware, filtration, measurement and control technology (including Belimo sensors with BACnet/Modbus), and gastronomy/kitchen ventilation. Felderer distributes third-party brands (Lindab, Trox, Schako, Helios, Maico, Ruck, Belimo, Norres) and produces own-brand constant airflow regulators and limiters (KVB, KCRK, RCCK, RCCK-D, RCQK, RCQK-D). Differentiated capabilities include web-based product configurators across eight categories, a 10+ year B2B online shop, Express Individual custom manufacturing, prefabricated assemblies with just-in-time delivery, mobile construction-site logistics with time-windowed delivery, a 360° project service covering concept-to-installation, and the Felderer Akademie training program.

Revenue mechanics combine one-time product sales (the core stream), custom manufacturing fees, project logistics services, and training services, with pricing hidden behind login/registration for verified commercial accounts and invoiced payment (Zahlung auf Rechnung). The go-to-market is sales-led through regional account managers at each location, layered on top of a mature direct e-commerce channel. Leadership comprises founder and Chairman Klaus-Philipp Felderer alongside Managing Director Thomas Degenkolb, with strategic and operational integration provided by Lindab Group ownership.
