PAPRs, where applicable, offer the user an alternative to tight-fitting respirators, thus eliminating the need for fit testing and associated costs. PAPRs also provide the comfort of moving filtered positive pressure airflow to help the user breathe easier during work activity. PureFlo brand PAPRs have the added bonus of having no cumbersome waist belts or hoses, plus options for complete respiratory, head, eye, and face protection combined.
A head-mounted PAPR is free of cumbersome waist belts and hoses, thus providing more freedom of movement and less risk of snagging on other equipment. The motor, filter, and batteries are all located within the head top of the head-mounted PAPR system. Waist-mounted PAPRs have the motor blower, filters, and batteries located on a belt. The air is filtered at the waist and delivered through a hose into the headtop.
The majority of PAPRs are loose-fitting systems, which do not require fit testing. Generally only PAPRs with a tight-fitting, acclusive mask would require a fit test.
Positive pressure is air fed into the headtop at a rate that keeps the air pressure within at a positive flow rate level at all times. Negative pressure respirators require a tight fit, as the user is required to breathe air into the respirator through a filter and without the assistance of battery-powered airflow.
PAPRs tend to be a matter of choice based on the hazards that are present for the tasks at hand. The breathing hazards, comfort level within tasks, and other protective needs such as face and head protection all play a part in the decision-making for what PAPR is right for you.
PureFlo 3000 - NIOSH Certified
The PureFlo 3000 is a loose-fitting, all-in-one powered air purifying respirator (also referred to as a PAPR) that provides integrated respiratory, face, head, and eye protection, with the option for hearing protection.
The PureFlo 3000 is an all-in-one head mounted PAPR with integrated protection approved to the following standards:
NIOSH 42CFR84, CSA standard Z94.4
Head Protection (Hard Hat):
ANSI/ISEA Z89.1:2014 Type 1 Class G
Face Shield/Eye Protection:
ANSI/ISEA Z87.1:2015 Impact Rated (Z87+)
IP54 (In Use) IP55 (Cleaning); IEC 60509:1989
The PureFlo 3000 is approved to NIOSH 42CFR84, CSA standard Z94.4 with an APF of 25 and 1000 when used with the Overhood.
The PureFlo 3000 has an APF of 25 (per OSHA assigned protection factor, federal register notice 71:50121-50192, dated 8/24/2006), and an APF of 1000 with Overhood.
The meaning of APF, as defined by OSHA, is the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program as specified by OSHA. Or, an APF is a term used by OSHA to determine how well a respirator/filter combination will protect an individual form external contaminants. It is an estimate of the level of protection a respirator provides.
The meaning of MUC as defined by OSHA, is the maximum atmospheric concentration of a hazardous substance from which an employee can be expected to be protected when wearing a respirator, and is determined by the assigned protection factor of the respirator or class of respirators and the exposure limit of the hazardous substance. The MUC can usually be determined mathematically by multiplying the assigned protection factor specified for a respirator by the permissible exposure limit (PEL), short-term exposure limit, ceiling limit, peak limit, or any other exposure limit used for the hazardous substance.
PureFlo 3000 HEPA filters are designed to remove 99.97% of airborne particles of 0.3 microns or greater in diameter.
Filter life depends on several factors: concentration levels of the dust or particulate in the area, particle size, humidity, etc. The electronics in the PureFlo 3000 monitor the filter and batteries.
The LED indicator on the unit will turn Red (instead of Green) alerting the worker when the filter is loaded and/or the batteries are low.
Once the HEPA filter is opened, it should be changed within 6 months regardless if it has been used or not. Even when the cartridge filter is not in use, but is unsealed, it will continue to absorb contaminants from the environment.
If the filter is unopened and safely stored in line with the manufacturer's instructions, they have a shelf life of up to 5 years from the date of manufacture.
Filters cannot be cleaned as this will damage the filter media, resulting in a loss of protection. It is highly recommended that a change-out schedule is in operation so you are aware of when each cartridge needs to be replaced.
The HEPA filter on the PureFlo 3000 will give the protection required to protect from crystalline silica dust.
No, The asbestos standard does not allow the use of loose-fitting respirators to be used inside the containment area.
Airborne lead protection factors while using the PureFlo 3000 PAPRs have shown to keep user blood lead levels to an acceptable level.
A pre-filter captures large particulates before they enter the main filter. This helps to extend the lifespan of the main filter and the PAPR.
Odor pre-filters have activated carbon cloth to provide the ability to remove low-level odors.
The air flow rate on the PureFlo 3000 is 220 L/min (170L/min minimum) : 7.8 CFM (6 CFM Minimum)
The PureFlo 3000 has 220 l/min initial flow rate and the LED indicator will turn Red instead of Green when it reaches its minimum requirement of 170 l/min.
The helmet on the PureFlo 3000 is constructed from ABS (Acrylonitrile Butadiene Styrene) plastic.
The PureFlo 3000 helmet has an in-use life of up to 5 years from the date of issue to the user (i.e. removal from storage). It is recommended that it is replaced after 5 years, or if the helmet is involved in an accident. Please also note that excessive wear and tear, together with use in extreme environments, can considerably reduce the lifespan of the hard hat.
Yes, the visor can be purchased as spare part. The visor simply unclips from the face shield, and a new visor is easily inserted. Learn more in our How-to Video.
The PureFlo 3000 is supplied with two Lithium-Ion batteries. Only one is used to operate the unit; the second is a spare.
Each battery will last between 4 – 5 hours.
If you work on the assumption that the battery is fully used and recharged in an ambient temperature of 71.6⁰F (22⁰C) every day, it is estimated that the battery would need to be replaced after 500 days or just over 15 months.
The batteries will take 2 hours to fully charge.
We would recommend that when charging the batteries you do not leave them in the charger for longer than is necessary.
There are four LED battery indicators.
- LED 1 flashing red indicates the temperature is too low or too high for charging, or that the battery has failed. When LED 1 is solid red the battery is charging.
- As the battery charges LED 2, 3, and 4 will light sequentially solid green until fully charged.
- If LED 1 flashes red, and LED 4 flashes green at the same time, the battery has failed.

The PureFlo 3000 uses Lithium-Ion batteries that do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles.
Yes, the PureFlo 3000 can be cleaned with a damp cloth or an alcohol-based wipe. The Purewipes (PR02054SP) are recommended for this purpose. However, DO NOT submerge the unit in water as this will damage the unit's electronics. For more information regarding cleaning the unit then please see our "How To" video.
Yes, self-adhesive stickers can be placed on the hard hat shell. However, please ensure that the adhesives on the stickers do not negatively affect the safety performance provided by the hard hat.
