Frequently Asked Questions – Flight DefendMe II Aerosol Evacuator
How often do I need to change the filters and what is the cost?
|Durability||Action /Cost Retail|
Washable Moisture Filter
Machine Wash or Replace
Fine Particulate Matter Filter
Main Filter H13 Hepa Filter
Activated Carbon Filter
What type of UV Light is it?
It is a UV-C Light. UVC has been shown to be effective at killing or inactivating microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
8 Watts Ultraviolet lamp
Can the Flight HEPA filter remove the Novel Coronavirus?
Standards require that a HEPA air filter must remove—from the air that passes through—at least 99.95% (European Standard) or 99.97% (ASME) of particles whose diameter is equal to 0.3 μm; with the filtration efficiency increasing for particle diameters both less than and greater than 0.3 μm. Therefore, HEPA Filters can definitely filter out the Coronavirus which are approximately 0.125 μm in size at close to 100% efficiency. The general misconception is that HEPA Filters work like a net or a sieve and block out particles of certain sizes. However that is incorrect. HEPA filters are designed to target particles much smaller than 0.1microns as these particles adhere to the fibers by diffusion at almost a 100% rate.
Can you use the DefendMe II as an Air Purifier?
It is not designed as an air purifier but theoretically it should be able to do the same thing. Our CFM is 250 CFM or it is able to Exchange the air in a room 15 times an hour (Rating based on a 10 x 10 x 10 Ft high room).
What is the (Air Change per Hour) ACH of the DEFENDME II?
(CFM x 60 minutes) / L x W x H (Cubic Feet)
= (250CFM x 60)/ 10 x 10 x 10ft
= 15 ACH
What is the CFM?
One of the most important specifications that determine the suctioning ability of the system is the airflow measured in CFM (Cubic Feet per Minute). The air flow will take into account the suction strength, the motor input power and the design of the unit. Therefore, the input power, typically measured in watts, or the suction strength, measured in Pascals (PA) will not be a good indication about the airflow of the suction unit by itself. However, when you look at the CFM specification of the unit, this value will provide a better indication of the suctioning ability of the unit as it takes all these factors into account.
The Flight DefendMe II has an airflow of 250 CFM.
What is the suction Power?
What is the Wattage?
The Flight DefendMe II is rated at 350W, which is the input power of the motor. The wattage refers to the power of the motor and not the performance of the machine, the higher power consumption does not mean better. Therefore, although our input power of our motor is lower than our competitors our airflow is higher.
How long is the pipe?
It is a 6 ft flexible pipe that can be positioned easily.
Are there different Lengths?
Not at this moment.
How big is the nozzle?
The nozzle is 6” Diameter. A wider nozzle design helps to capture more aerosols.
What is the size of the machine?
16 x 12 x 22” (L x W x H)
What are the Shipping Dimensions?
- 21 x 16 x 29” – 64lbs
- 18 x 18 x 8” – 10lbs
What is the shipping weight?
Does the unit have wheels?
The unit has 4 Lockable wheels?
What is the warranty?
3 year Warranty
How loud is the DefendMe?
The DefendMe is rated at 59DB; this is at max speed (10). The noise level can be reduced by turning down the speed. As a reference, normal conversation is approximately 60 db.
Why do some of the competitors have higher Suction values?
Suction power (Negative Pressure) is based on the flow (CFM) through an opening. Typically reducing pipe size will increase suction power and reduce CFM. CFM is the most important value as that determines the volume of Aerosols the machine can evacuate.
