Best Fireplace Fan Blower Kits for Model-Specific and Universal Setups
The best fireplace fan blower kit is one that matches your fireplace’s required part number, dimensions, and mounting arrangement. The Hiorucet GFK4B is best for compatible GFK4-series replacements, while the Criditpid GFK-160A suits listed 160-CFM applications and the Criditpid FK24 targets compatible Majestic-style fireplaces. AC Infinity is an option for buyers seeking smart controls, but check fit before choosing a universal-style kit.

Hiorucet GFK4B Blower Fan Kit
This kit is best for owners whose fireplace calls for GFK4, GFK4A, GFK4B, or FK4 replacement parts. Its listed cross-references also include Rotom HB-RB74K and R7-RB74K, with several fireplace brands and models identified in the product name. Confirm the exact model and required part number before ordering.
The 120-volt kit is rated at 130 CFM and includes a variable-speed control, magnetic thermostat, three-prong cord, prewired harness, and foam pads. The thermostat is described as opening around 120°F and closing around 90°F to control automatic operation. Choose this if you need a GFK4-series match with included controls and mounting pads. Its airflow is lower than the 160-CFM kits in this comparison.
Criditpid GFK-160A Dual Blower Kit
This is best for buyers with a fireplace that matches the GFK-160A cross-references, including listed Heat N Glo, Quadra-Fire, Heatilator, Superior, and other models. The product specifies 160 CFM, dual blowers, and ball bearings. It includes a magnetic thermostat, rheostat speed control, three-prong cord, rubber mounting feet, and prewired harness.
The listed dimensions are approximately 12 13/16 by 4 5/16 by 4 5/16 inches, and the cord is 83 inches long. The thermostat is specified at 120°/90°. Choose this kit over a 130-CFM option if your model calls for this assembly and the listed airflow fits your replacement needs. Do not rely on brand name alone: the product lists many cross-reference numbers, so verify the exact part and available mounting space.
Criditpid FK24 Fireplace Blower Kit
The FK24 is best for a compatible fireplace requiring FK24, 54103, Rotom HB-RB65, or another listed cross-reference. The product names several Majestic, Martin, Temco, and Vermont Castings models. Its specifications include 130 CFM, 120 volts, 35 watts, and a sealed ball-bearing motor.
The kit includes a galvanized mounting bracket, speed control, magnetic thermostat, noise-reduction padding, and installation instructions. Its thermostat is listed at 120°/90°, and the motor insulation is Class H, rated in the product details to 392°F. Choose this if your existing assembly matches the FK24 reference and you need the supplied bracket. Avoid choosing it solely because your fireplace is from a listed brand; model-level fit still matters.
AC Infinity AIRBLAZE T10 Universal Kit
This 10-inch fan kit is best for buyers prioritizing smart controls and adjustable operating schedules. Its listed features include temperature and humidity programming, timers, cycles, scheduling, minimum-speed settings, and Wi-Fi app access for programs, alarms, notifications, and climate data.
Unlike the model-specific replacement kits above, the supplied information does not give a fireplace-model cross-reference, airflow rating, or detailed mounting dimensions. Check the fan’s size and installation requirements against your fireplace before buying. Choose this if app-connected controls are important; avoid assuming that “universal” means it fits every fireplace.
Adviace GFK-160A Fireplace Blower Kit
This is another option for fireplaces matching the GFK-160 or GFK-160A family and its listed cross-references. It is best for buyers who want a 160-CFM ball-bearing blower with rubber isolation feet. The kit also includes a magnetic automatic thermostat, rheostat controller, grounded three-prong cord, wire harness, and instructions.
The listed dimensions are 12 13/16 by 4 5/16 by 4 5/16 inches; the thermostat is specified at 120°/90°. Rubber feet are intended to reduce noise and vibration. Compare this kit’s dimensions and part references with the Criditpid GFK-160A before deciding: both list 160 CFM, but the exact replacement match should guide the choice. This product’s listed motor speed is 2700 RPM.
Buying Guide: How To Choose A Fireplace Blower Kit
Which replacement part number should I match?
Start with the fireplace’s model label, existing blower, or owner documentation. Compare the required part number with the kit’s cross-reference list. A shared brand name is not enough to establish fit because one manufacturer may use different blower assemblies across models.
How do airflow and dimensions affect the choice?
Compare the stated CFM with the replacement specification, then measure the available mounting area and outlet clearance. The kits here list 130 or 160 CFM, while the AC Infinity listing identifies a 10-inch fan but does not provide a CFM figure. Do not treat a higher CFM number as proof of compatibility.
Do I need a thermostat and speed control?
A magnetic thermostat can switch a blower on and off as the fireplace area warms and cools. A rheostat lets the user adjust fan speed. Check whether these controls are included and whether their listed temperature settings align with the replacement kit you need.
What should I check before installation?
Verify the kit’s dimensions, voltage, cord arrangement, mounting method, and included harness against your fireplace requirements. Follow the product instructions and fireplace documentation. If the model or wiring is uncertain, consult a qualified fireplace technician.
Frequently Asked Questions
Are fireplace blower kits interchangeable?
No. Kits can differ in dimensions, wiring, brackets, airflow, and part references. Match the fireplace model and replacement number before purchase.
What does a magnetic thermostat do?
It senses heat near the fireplace and can automatically switch the blower on and off at its specified temperature thresholds.
Is 160 CFM always better than 130 CFM?
Not necessarily. Choose the airflow specified for your fireplace. A higher CFM rating does not ensure proper fit or operation.
Can I install a blower kit in any fireplace?
No. Fireplace designs and blower clearances vary. Confirm compatibility, mounting space, and installation requirements for the specific model.
