Sourcing high performance registers
For a Vermont home (zone 6A), I using Fujitsu slim-duct systems to distribute air to multiple rooms. To balance the distribution system, instead of using dampers on branches, I am planning to use registers with flow modulation (such as opposed blade dampers).
My local supply-houses do not have opposed blade damper registers in stock (such as Truaire 210VO series, or Truaire 300 series).
Can any GBA readers suggest of if
1. the “damper at the register” strategy works?
2. Is there any supply-house that can ship these?
3. How much penalty in pressure drop and flow modulation I will pay for using multi-shutter damper registers?
Thanks in advance!
