Checking those details up front helps prevent weak airflow, unstable humidity, incompatible controls, excess heat, odor leaks, and extra replacement purchases after the grow space is already running. Also review filter replacement intervals, probe placement, duct access, cleaning requirements, controller expansion limits, and manufacturer warranty coverage so the system stays practical after installation and remains easy to service during normal grow cycles.\u003c\/p\u003e","products":[{"product_id":"spider-farmer-4-inline-duct-fan-w-speed-controller","title":"Spider Farmer 4\" Inline Duct Fan w\/ Speed Controller","description":"\u003ch6\u003eDescription\u003c\/h6\u003e\n\u003cli\u003eAn inline fan improves airflow, regulates temperature and humidity, and helps plants grow stronger.

Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. It is built with a PWM-controlled EC motor 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. Includes a smart controller with dynamic climate and time-based programming and can connect to multiple UIS devices. This product is a part of the UIS platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.\u003c\/li\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmart Controller: \u003c\/strong\u003eCONTROLLER 69 PRO features smart programming that not only has basic temperature, humidity, and VPD triggers but also allows you to set dynamic fan speeds that would respond based on their changes. Go even further by setting a minimum speed that the fan will run at constantly and would only increase when triggered. Timer, cycle, and schedule modes add custom on-demand activation for various uses. Securely connect to the AC Infinity app through Wi-Fi to utilize automation capabilities from anywhere throughout the day. Access your fan remotely, unlock advance programs, set notifications, view historical climate charts, and export CSV data. This controller can connect to up to four UIS devices which includes products like the CLOUDLINE, CLOUDRAY, and IONFRAME Series. It can also connect to your favorite grow light and outlet device from outside the UIS platform using select adapters.\u003c\/li\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuiet and Energy Efficient Design: \u003c\/strong\u003eUnlike common duct fans that use an AC motor which is loud and unmanageable, this duct fan features an EC motor that is controlled using PWM (Pulse Width Modulation). This technology enables motors to be able to run smoothly at extremely low RPM speeds without generating additional heat or noise. In addition, the duct fan uses a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.\u003c\/li\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications: \u003c\/strong\u003eThis quiet duct fan system is popular in a variety of applications including cooling AV equipment rooms, closets, racks, and cabinets.

Each fan uses an easy-to-use knob controller that adjusts fan speed for your specific airflow boosting needs. It features a unibody framework that helps reduce vibration and ensures smooth and low-resistant airflow. The matte black steel cylinder is fluted and ridged for easy and secure installation in-between ducting. Its balanced steel blades have a 67,000-hour lifespan and spin using permanently lubricated dual-ball bearings to eliminate regular maintenance. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. This kit includes one AC powered inline booster duct fan, a speed controller with a power plug, mounting screws, and a cable management set.\u003c\/li\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed Controller: \u003c\/strong\u003eThe inline variable speed controller can control the fan's speed and turn it on or off. Turning the knob will increase or decrease the fan speed and optimize airflow and noise levels for your application. Its speed range includes a low, medium and high threshold, producing up to 106 CFM and 28 dBA in noise. This speed controller uses a female aviation plug with a metal retainer, tightly securing its connection to the booster duct fan.\u003c\/li\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications: \u003c\/strong\u003eThis versatile inline booster fan is made to be installed in between ducting for various applications that need improved air delivery. In households, it boosts airflow from HVAC units to remove stale air and odor, ventilating attics, workshops, kitchens, basements etc. In grow tents, grow rooms, and indoor gardens, it's primarily used as an intake fan to bring in fresh air. Please note this booster fan cannot be used standalone in high static pressure applications like room ventilation. Additionally, it is not suitable for use in applications with restricted airflow like systems that use carbon filters.
