The best choice depends on whether you need to replace air exhausted from a building or simply heat and cool a room. The Captive-Aire blower assembly and FICBXRA rooftop fan are the closest matches for makeup-air applications; the three PTACs provide room heating and cooling but are not listed as outdoor-air makeup units. The comparison below highlights each product’s stated capacity and key installation considerations so you can distinguish fresh-air equipment from room-conditioning options.
| Product | Best suited for | Key stated feature |
|---|---|---|
| Captive-Aire G15 blower assembly | Makeup-air system builders | 2000–7500 CFM blower assembly |
| FICBXRA rooftop supply fan | Filtered rooftop air supply | 2875 CFM, 1 HP motor |
| OLMO 12,000 BTU PTAC | Room heating and cooling | 3.5 kW electric heater |
| Amana 15,000 BTU PTAC | Room conditioning with heat-pump operation | Heat pump plus 3.5 kW electric heat |
| Cooper & Hunter 12,000 BTU PTAC | Room heating and cooling | 3.5 kW electric heater |
Captive-Aire G15 Makeup Air Blower Assembly
This blower assembly is best for buyers assembling or servicing a makeup-air system who need a blower component rather than a complete packaged rooftop unit. Its stated airflow range is 2000–7500 CFM, and it includes a motor mounting plate and mounting hardware. The forward-curved, double-inlet design has pillow-block ball bearings, a galvanized finish, and base feet that can be mounted for different discharge positions.
Why it stands out: The broad stated airflow range and adjustable discharge positioning make it a flexible component for system planning. Limitation: The listing describes a blower assembly, not a complete heated makeup-air unit. A motor and other system components may need to be sourced separately; confirm what is included before purchase.
FICBXRA 2875 CFM Rooftop Supply Fan
This fan is best for buyers who need a packaged rooftop or sidewall fresh-air supply fan with filtration. It has a 16-inch blower, a 1 HP, 110V single-phase motor, and a stated airflow of 2875 CFM. The galvanized steel housing is described as weather resistant, and the unit includes a removable aluminum mesh filter with a large surface area.
Why it stands out: The intake hood and filter make it a closer fit for supplying outdoor air than a room PTAC. Limitation: The listed features do not specify a heating element, so do not assume this fan heats incoming air. The listing also says it cannot be used with a speed controller.
OLMO 12,000 BTU PTAC With Electric Heat
This OLMO PTAC is best for buyers seeking heating and cooling for a room, such as a hotel room, rental, or residential space. It combines 12,000 BTU cooling with a 3.5 kW electric heater and dehumidifier function. The listed system uses 230/208V, single-phase, 60Hz power and includes a 20A plug with a reset breaker.
Why it stands out: It provides both room cooling and electric heat in one packaged terminal unit. Limitation: A PTAC is not identified as a makeup-air unit and should not be treated as equipment for replacing exhausted outdoor air. For a new installation, the wall sleeve and exterior grille are required but not included. Verify the receptacle before ordering.
Amana 15,000 BTU PTAC Heat Pump
This Amana PTAC is best for buyers who want a room-conditioning unit with heat-pump operation and electric backup heat. The listed cooling capacity is 14,500/14,700 BTU, with 13,200/13,500 BTU heat-pump heating and 3.5 kW electric heat. Features include three fan speeds, fan-only mode, a Fahrenheit/Celsius display, wired thermostat compatibility, and automatic emergency heat.
Why it stands out: Its heat pump and electric backup offer more listed heating modes than a basic electric-heat-only PTAC. Limitation: It is a room PTAC, not a stated outdoor-air makeup unit. The included 20-amp power cord also means buyers should check electrical requirements for their installation.
Cooper & Hunter 12,000 BTU PTAC
This Cooper & Hunter PTAC is best for buyers furnishing a room that needs packaged heating and cooling, including apartments, homes, dorms, or hospitality spaces. It provides 12,000 BTU cooling and a 3.5 kW electric heater, uses R-32 refrigerant, and is designed for 230/208V, single-phase, 60Hz power with a 20A plug and reset breaker.
Why it stands out: Its listed use cases and combined cooling and electric heat suit individual rooms. Limitation: The listing does not describe it as a makeup-air system. New installations need a wall sleeve and exterior grille, which are not included; confirm electrical compatibility before ordering.
Buying Guide: How To Choose A Heated Makeup Air Unit
Do you need outdoor-air replacement or room heating?
Makeup air replaces air removed by exhaust equipment, helping maintain airflow balance. A PTAC heats and cools a room; the product details here do not identify the PTACs as makeup-air units. If your goal is to supply outdoor air, focus on equipment explicitly designed for that function and verify whether heating is included.
What airflow capacity should you compare?
Compare the required airflow in cubic feet per minute (CFM) with the equipment’s stated capacity. The Captive-Aire assembly lists 2000–7500 CFM, while the FICBXRA fan lists 2875 CFM. These figures alone do not determine suitability: the project’s exhaust rate, duct layout, and system design also matter.
Is the incoming air heated?
Check for a clearly specified heating component and its capacity. The FICBXRA features provided here describe a fan and filter but do not state a heater. The PTACs list electric heating, but they are room-conditioning products rather than identified makeup-air equipment. Do not assume that a fan warms incoming air.
What installation details should you verify?
Confirm voltage, phase, amperage, mounting location, and included components. For the PTACs, verify the receptacle and account for required sleeves and grilles where applicable. For blower assemblies, determine whether the motor and other system parts are included. Have a qualified HVAC professional evaluate the application and installation requirements.
Frequently Asked Questions
What does a makeup air unit do?
A makeup-air unit supplies replacement air to a building when exhaust fans or other equipment remove indoor air. Some systems heat that incoming air, but heating capability must be confirmed in the product specifications.
Can a PTAC serve as a heated makeup-air unit?
These PTAC listings describe room heating and cooling, not outdoor-air replacement. Do not choose one as a makeup-air unit unless the manufacturer confirms it is designed for that use.
Does the FICBXRA fan include heat?
The supplied product features state its airflow, motor, housing, and filter but do not list a heating element. Verify heating options with the seller or manufacturer before purchase.
What is the difference between the Captive-Aire and FICBXRA products?
The Captive-Aire listing is a blower assembly with a stated 2000–7500 CFM range. The FICBXRA is a rooftop or sidewall supply fan listing with a stated 2875 CFM capacity, intake hood, and filter.
