Equipment Overview

The INFINAIR YFRUD is a high-performance unit configured for rooftop air extraction via a vertical discharge system, preventing the accumulation of hot or contaminated air on the roof surface. Its design is based on a double-section cylindrical structure that optimizes flow trajectory.

The impeller, made of a single-piece cast aluminum, features variable-pitch airfoil blades, allowing the fan to be precisely tailored to each system's requirements. Additionally, its 2.5 mm continuous-weld cold-rolled steel casing ensures extreme durability and total weather protection

Competitive Advantages

  • Rainproof Design: Includes an internal rainproof damper that protects the motor and enhances discharge force.
  • Structural Safety: Single-piece cast aluminum impeller for maximum operational reliability and safety, even at speeds 120% above nominal.
  • Acabado premium: Surface polishing to remove burrs and exposed welds, followed by a high-quality electrostatic epoxy coating.
  • Traceability: Permanent aluminum nameplate with a unique serial number for each unit.
  • Mechanical Reliability: Direct-drive motor with a power reserve coefficient exceeding 110%

Technical Specifications

  • Fan type: Vertical upblast axial.
  • Airflow range: 1,000 ~ 100,000 m³/h (588 ~ 58,824 CFM).
  • Static pressure range: 100 ~ 1,200 Pa (0.4 ~ 4.8 in.WG).
  • Drive type: Direct.
  • Mounting: Rooftop curb-mounted
  • Balancing quality: Grade G2.5 in accordance with AMCA 204 standard.
  • Motor: IP55 rating, Class F insulation, with sealed, maintenance-free bearings.
  • principal Aplications: General rooftop exhaust (commercial and industrial), ventilation systems for buildings requiring high, upward air discharge.
