Does this replacement motor fit both the MARK-15 and MARK-15V?
This product is intended for the MARK-15 and MARK-15V commercial air cleaners. Confirm the model and existing motor specifications before installation.
What are the motor specifications?
The replacement motor is specified as 1/3 HP and 120V. RPM, amperage, frequency, phase, rotation, and other motor-specific electrical data require verification.
Will replacing the motor restore the air cleaner's airflow?
A functioning motor is necessary for proper blower operation. Replacing a failed or worn motor can restore operation when the motor is the cause of the problem. The complete MARK-15 and MARK-15V systems are rated for 1,050–1,250 CFM, but actual airflow also depends on the blower, filters, and overall system condition.
How do I know if my MARK-15 motor needs replacement?
Possible signs include a motor that will not start, abnormal noise, excessive vibration, intermittent operation, or loss of airflow. These symptoms can have other causes, so troubleshoot the complete unit before ordering a replacement motor.
Does this motor work with the MARK-15V V-Bank model?
Yes, this replacement is intended for the MARK-15V as well as the standard MARK-15. The MARK-15V differs mainly in its filtration configuration, using an 18 lb carbon V-Bank for odor control.
Can I install the replacement motor myself?
Motor replacement requires access to the internal electrical and blower components. Commercial installations should be serviced by a qualified technician, particularly when electrical connections are involved.
Should I replace the filters when replacing the motor?
Not automatically. However, this is a good time to inspect them. Dirty filters can restrict airflow and increase the load on the blower system. MARK-15 pre-filters are normally replaced monthly, carbon filters about every two months, and the high-efficiency filter annually under typical conditions.
What filters does the MARK-15V use?
The MARK-15V uses a pre-filter, an 18 lb activated-carbon V-Bank, and a high-efficiency main filter. The V-Bank carbon filter is listed for replacement approximately annually, with actual life depending on use and contaminant load.
Is this a complete MARK-15 or MARK-15V air cleaner?
No. This is a replacement motor only for compatible existing MARK-15 and MARK-15V air cleaners.
What should I check before ordering?
Confirm your air-cleaner model, supply voltage, existing motor specifications, and the cause of the equipment failure. If you are unsure, contact us before ordering.
