Description
Deliver professional-grade, brand-matched zoning performance for Rheem® and Ruud® EcoNet® communicating HVAC systems with the iO HVAC Controls RM-XX Round Zone Damper — a rugged, precision-engineered motorized damper purpose-built for EcoNet zone panel installations. Designed for HVAC contractors handling new construction, zoning retrofits, and service-replacement jobs, the RM-XX drops cleanly into round branch-duct applications while delivering the exact 3-wire power-open / power-close control sequence required by Rheem and Ruud EcoNet zone systems — no adapters, no workarounds, no compatibility guesswork.
Constructed with a heavy-duty 22-gauge steel shell, the RM-XX round damper is engineered for long service life in demanding residential and light commercial supply-duct applications. The galvanized steel housing resists corrosion, holds tight dimensional tolerances for clean slip-fit duct connections, and provides a durable mounting platform for precision actuator performance over years of zone cycling. Each damper ships equipped with a genuine Belimo® 24VAC actuator — the industry’s most trusted name in HVAC damper actuation — delivering 18 lb-in of torque, 35-second stroke timing, and just 2.5 VA power draw for smooth, quiet, and energy-efficient operation.
Available in standard round sizes from 4″ through 18″, the RM-XX covers the full spectrum of branch and trunk duct diameters found in typical residential and light commercial zoning systems. A simple built-in minimum position adjustment lets technicians fine-tune bleed airflow for static pressure management — a critical feature for preventing equipment short-cycling, protecting compressor and blower components, and reducing duct noise when zones are partially or fully closed.
Backed by a 5-year warranty and available with same-day shipping from iO HVAC Controls’ Indianapolis, IN distribution center, the RM-XX is the professional installer’s first-choice round damper for fast, reliable EcoNet-compatible zoning jobs.
Features:
- Native Rheem® & Ruud® EcoNet® Compatibility — Engineered specifically for the 3-wire power-open / power-close control protocol used by Rheem and Ruud EcoNet communicating zone control systems — no adapters, no reprogramming, no protocol translation required.
- Genuine Belimo® Actuator — Every RM-XX ships with a factory-installed Belimo actuator, the industry’s gold standard for HVAC damper actuation — trusted for reliability, quiet operation, and long service life.
- Rugged 22-Gauge Steel Shell — Heavy-duty galvanized steel housing resists corrosion, holds tight tolerances for clean slip-fit duct connections, and delivers long-term structural durability.
- Wide Size Range — 4″ to 18″ Round — Standard round sizes cover virtually every branch and trunk duct application in residential and light commercial zoning systems; custom sizes available on request.
- 3-Wire Power-Open / Power-Close Control — Positive-drive bidirectional actuation ensures reliable, deterministic damper positioning in both directions — no spring-return failure modes to worry about.
- 24VAC / 2.5 VA Low-Voltage Operation — Minimal current draw supports multi-zone, multi-damper installations without transformer upgrades.
- 18 lb-in Actuator Torque — Strong torque output drives the damper blade smoothly against typical residential and light commercial static pressures.
- 35-Second Stroke Timing — Fast, controlled open/close cycles reduce HVAC system response lag while preventing ballistic slam that can damage blade seals over time.
- Built-In Minimum Position Adjustment — Field-adjustable bleed setting prevents equipment short-cycling, manages static pressure, and reduces duct noise in small or closed zones.
- Compact Actuator Profile — Slim motor housing (2.75″ depth × 2.5″ height projection) fits cleanly in tight joist bays and mechanical spaces.
- Same-Day Shipping from U.S. Stock — Large inventory of standard sizes ships same-day from iO HVAC Controls’ Indianapolis warehouse — keeping contractor jobs on schedule.
- 5-Year Warranty — Professional-grade warranty coverage backs the RM-XX for long-term contractor and homeowner peace of mind.
- Retrofit-Ready — Available in retrofit configurations for service replacements — ask iO HVAC Controls about retrofit options for existing installations.
Applications:
- Rheem® EcoNet® zoning systems — new construction, retrofit, and service replacement dampers
