UPGRADED LASER EXHAUST INLINE DUCT FAN with TEMPERATURE & HUMIDITY CONTROL by AC INFINITY

  • Designed to quietly ventilate laser engraver machines and quickly expel exhaust odors and fumes created from reductive laser engraving applications.
  • Intelligent controller with temperature and humidity programming, fan speed control, timer, and alarm system.
  • Mixed flow design combined with a PWM-controlled EC-motor for truly quiet and energy-efficient performance.
  • Duct Size: 4” | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 205 CFM | Noise: 28 dBA | Bearings: Dual Ball

ADVANCED EXHAUST FEATURES:

One of the most consistently utilized upgrades for OMTech laser machines, this duct fan system provides quiet exhaust and ventilation to laser engraving applications. The inline mixed-flow design maintains airflow even in high static pressure applications. It contains an EC motor with PWM control for quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. It includes an intelligent controller with advanced programming and functionality.

INTELLIGENT CONTROLLER:

 The controller can be programmed to adjust fan speeds to respond to varying high and low temperatures and humidity. The controller can be set to run continuously or triggered to run at customizable speeds when given power for ventilation applications, thanks to its backup memory capability. Additional features include a countdown timer, alarm system, and eco-mode. Includes detachable 12-foot precision probe that is water-resistant. This EC smart controller can power and control 2 inline duct fans of any size, such as this CLOUDLINE T4 with a CLOUDLINE S6.

QUIET & ENERGY-EFFICIENT DESIGN:

Unlike common duct fans that use AC motors which are loud and unmanageable, this duct fan features an EC motor controlled with PWM (Pulse Width Modulation) for smooth performance at extremely low RPM speeds without excess heat or noise. A mixed-flow design with stator blade and dual hydrodynamic wind circles provides a high static pressure rating for strong airflow, even in restricted air movement applications. The motor houses dual ball bearings with a 67,000 hour lifetime which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated for high resistance to dust and liquids and performs well even in harsh environments.

Nice shelves that will work with some modifications
Item Package Quantity: 1, Size: 6 Tiers, Item Package Quantity: 1, Size: 6 Tiers
Pay attention to the bottom shelf and where it is relative to the floor. It’s only about 6 inches, which isn’t good for a retail environment. I swapped the bottom nipples out for some 10” nipples and the results were night and day. So much better now.

Good shelves
Item Package Quantity: 1, Size: 6 Tiers
Unit was pretty easy to assemble. Shelves are sturdy and no scratches or dings. My only complaint is that there is paint missing here and there on the black pipe. We covered those spots with magic marker. I would buy it again!
