What Medical Professionals Say

Any More Queries?

Frequently Asked Questions

General Questions

Is the device certified?

Yes, the device is tested by Intertek according to IEC 60601-1 international medical device safety standards.

What is the purpose of this device?

The main purpose of this device is to provide an effective yet protective measure of ventilation for an individual that wears a PPE suit.

How does the device work?

The working of the device is based on the principle of fundamental laws of thermodynamics and energy conservation. The device is equipped with appropriate electronic components which enable it to suck in air from the surrounding outside and pump it inside the suit. Keeping user safety in mind, the device is cleverly designed to filter the air before pumping it inside. Consequently, the hot and humid air inside the suit is forcefully pushed out. Due to this, a continuous flow of fresh, filtered and ambient air is maintained inside the PPE suit. As the suit now has developed a positive pressure inside, it also reduces the chances of any contamination from outside to enter into the suit.

Who can use this device?

There is no limit to who can use this device. It can be utilised by anyone who wears a PPE suit and requires a proper ventilation system like doctors, health care professionals, sanitary workers, people visiting patients, lab technicians, caregivers in hospitals, drivers and so on. We also plan on expanding the usage of the device as a personal cooling product.

Does the device come with warranty?

Yes, the device comes with a 6 month warranty against manufacturing defects. The basic do's and dont's as well as general instructions for proper usage of the device will be provided in the user manual.

Does the device come with a belt?

Yes, the device will come with a belt. It is designed by keeping universal belts in mind so the user can also use any belt that they already own and are comfortable wearing.

How do I use the device?

Where is this device worn?

The device is to be worn like a belt around the waist.

How do I wear the device?

The device can easily be worn using a few simple steps : 1. Loosen the side screw in the circular cap to remove the cap. 2. Wear the device around your waist using a belt and position the unit around the center of your back. 3. Position the hole of the PPE suit over the cylindrical part of the unit and place one of the filters provided on top of it. 4. Push the cap in from the top (outside of the PPE suit) and tighten the side screw to ensure sealing between the device, filter and PPE suit. 5. Switch the power on by pressing the click switch inside the pouch and turn the speed adjustment knob to zero. This will initialize the rushless motor. You will hear an extended beeping sound. 6. Adjust the knob to your desired speed and you are ready to use the device.

Does it require any special kind of PPE suit?

No, it does not require any different kind of PPE suit. However, it does require a tiny alteration in the normal PPE suit for the main unit to come out of. We provide an option where you can buy PPE suits from us with the device or you can contact any seller from where you regularly buy the PPE suit and get the alteration done. The details of the alteration will be supplied with the user manual once you buy our product.

How to sanitize the device?

The device is designed to have minimum surface area exposed on the outside of the suit. However, for additional safety the device can be sanitized using standard alcohol-based fluids as it does not have any exposed electronics. One can also use UV light. The detailed instructions for sanitizing will be provided in the user manual once you purchase the product.

How often does the device need to be sanitized?

We recommend that the device should be sanitized daily after use. The detailed instructions for sanitizing will be provided in the user manual after you purchase the product.
More About Tech Specs

What is Pulse Width Modulation Technology?

Pulse Width Modulation (PWM) is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The main advantage of PWM is that power loss in the switching devices is very low. The speed of the motor is effectively controlled without any resistive loses. PWM Technology allows the user to choose any speed according to their need and comfort.

How does the propulsion system work?

The device is equipped with carefully designed propellers and a Powerful Brushless motor capable of reaching RPM as high as 10,000.

What is Direct-Flow technology?

User experience was the top priority kept in mind while designing the device, CovTech-Ventilation System. During clinical trials and testings, we realized that the major areas of perspiration were back and thighs. Hence, the direct-flow feature was incorporated which essentiallyallows the user to change the angle of the blower unit, effectively delivering air to the desired area of discomfort as required.
More About Filters

What kind of filters have been used?

This device comes in two versions: 1. N95 Equivalent 3-Ply Filter - This filter is made up of 3-Ply material which consists of three layers, including an outer water-resistent layer, a middle melt-blown layer than is predominantly know for filtration of airbone particles and absorption of moisture and an inner soft absorbent non-woven layer. It is specifically designed to prevent patient to doctor infections. This provides more than 95% efficiency in the process of filtration of harmful particulate matter which is absolutely necessay in high risk areas like Covid-19 wards. It successfully blocks particles upto 0.3 microns. 2. P100 Filter - The NIOSH (National Institute for Occupational Safety and Health) approved, P100 filter which is currently under development is specially being designed to filter out particles which would give the device a very impressive and successful, 99.7% filtration efficiency. The P100 Filter is strongly resistant to oil particles and is considered to be the highest rating for personal respiratory protection.

How often do the filters need to be changed?

We recommend you change the filters daily if you are a health care worker. For critical service providers one filter can be used for up to three days. Again, this is subjective to the level of contamination in an environment that one uses the device in.

Where can I get extra filters?

We sell whole sale packs of filters separately. However, we provide 30 filters free with your first purchase.

When will the P100 filter version be launched?

The P100 filter version of the product is currently in the process of development to get the best possible filtration efficiency for you. We hope to be able to launch it as soon as possible. Until then, buy our current device.

What is Balance Charging Technology?

Battery balancing refer to technique that improves the available capacity of a battery pack with multiple cells and increase each cell's longevity. This process will ensure that the voltages of each individual cell in your battery have the same voltage. This is a critical factor to monitor as, if one of the cells voltage increases or drops below the required voltage range, the battery could get damaged.

How long can I use the device for?

The device which is equipped with a high power Lithium-ion battery, has been tested to last for about 6 hours. This ensures that an individual can use the device for a very long time.

How long does the device take to charge?

The device is equipped with a 2A charger and Balance Charging Technology that in turn, enables it for a speedy charge in about 4 hours so you can use the device everyday for your comfort and protection.

Is there a variant with a longer battery duration?

No. Keeping ergonomics in mind, we don’t supply a device with a larger battery pack. However, you can call us and let us know your specific need for a longer battery duration and we will be glad to assist you.

How many battery cycles does the battery last?

The batteries have been tested to last at nominal voltage for upto 750 cycles. Considering a rate of one cycle per day, the battery can last without any voltage drop for approximately 2 years!

Are there any risks with the high-power lithium-ion batteries?

No. Each individual lithium-ion battery pack comes with a pre-installed battery protection circuit. This circuit protects the battery from overcharging, overdischarging, short circuit and other such malfunctions. You can find detailed DO’s and DON’Ts in our user manual supplied with the product.
