Air Filters IAQ
Why should I opt for disposable filters instead of washable filters?
How can I choose the right filters for my facility?
How do I know when to replace the filter?
As alerts and warning to replace the filter will be sent through push notifications.
Can I outsource my complete filter management to some experts?
How can I upgrade my air filtration system?
You can also deploy recirculation unit like AAF AstroPure in defined areas to improve the Air Quality levels in the zone
Are your filters environment friendly?
Our distinguished range of filters also meets LEED Certification for efficiency and environment friendly criteria.
Ask AAF Representative for the right selection of filters
Is glass fiber material that is used as a filter media hazardous?
Our medias do not gets classified under OSHA defined hazards.
AAF recommends using PPE kits to handle any filters irrespective of the construction and materials of the filter
Are washable filters more environment friendly or disposable filters?
(1) Disposable filters are made up of completely incinerable material.
(2) Pressure drop and energy consumption of the disposable filters is lesser than washable filters.
Do you help us in disposing the filters?
AAF does not take any contract for filter disposal.
How do you help me arrive at TCO calculation for the investment on filters?
Indoor Air Quality IAQ
How do I measure Indoor Air Quality?
Can I subscribe to Indoor Air Quality services?
Contact AAF Sales or Marketing team for more information
How do I bring business relevance to the investment I make in Indoor Air Quality improvement?
Is there a platform where I can share the real time Indoor Air Quality with my employees
Are there standards for Indoor Air Quality?
For Prefilters to Fine Filters, we have: ASHRAE 52.2, EN779, and ISO 16890.
For HEPA Filters, we have EN1822 and ISO 29463.
Can the performance of Indoor Air Quality be committed?
What kind of dash boards can facility manager can have for Indoor Air Quality?
How can I make invisible Indoor Air Quality visible?
How can I have my facility surveyed for Indoor Air Quality?
What are the parameters I should monitor to improve in Indoor Air Quality?
Pharma Clean Room IAQ
How do you ensure the performance of the filter and how do you test the performance?
(1)For Prefilters, we have ASHRAE 52.2, EN779 and ISO 16890.
(2)For the High Efficiency filters, we have EN1822 and ISO 29463.
All the filters AAF manufactures comply to the respective standards.
What manufacturing standards do you follow to ensure the desired filter quality?
Do you test filters for EN1822 standard?
Is every HEPA filter that is manufactured tested for EN1822?
Ask AAF representative for Auto scan Certified HEPA filters.
What is the life of HEPA filters?
Filters gets classified under consumable commodity, hence life of the HEPA depends on usage condition
What kind of storage life do the HEPA filters have?
What kind of maintenance is needed for HEPA filters?
Are your HEPA filters classified as per clean room classification?
Generally, cleanroom prefers using below types as per IEST RP CC001 (Ref. Fig 1). Filter which follows these could be selected from the EN1822 or ISO29463.
As per ISO14644 for the cleanroom classification, particle size distribution must be maintained as per the figure 2. Only higher efficiency filters can match these.
What kind of equipment do you have for cleanroom application?
For Floor Standing applications, we have AstroPure series.
Does glass fiber media provide durability against moisture?
What is alternative for glass fiber media for better strength and better pressure drop?
Do you customize the filter size?
Do you provide solution for exhaust application in pharma?
The self- contained system makes filter removal and installation contact free using Silicone bag, external or easy locking mechanism for leak free sealing and full face scanning probe action to qualify aerosol challenge through the filters.
Do you also help with validation of the filters?
Micro Electronics Clean Room IAQ
Are your FFUs compatible with BMS?
A total of 240 nos. of AstroFan FFUs can be controlled with BMS connectivity at once. AAF eLisa can help you with interface for the control.
What kind of logics can we build to automate FFU operations?
What kind of service support you have?
Contact AAF Sales and Marketing Representatives for more information
How is laminar air flow ensured through your FFUs?
Do FFUs provide flow and velocity control?
AstroFan FFU EC units can be regulated for the flow and desired velocity through the electronic communication signals
Gas Phase Filters IAQ
How do I eliminate gaseous contaminants from my facility?
Media is impregnated with chemicals to handle specific gaseous contaminants.
How do Gas Phase filters work?
Why are Gas Phase Filters required in HVAC?
What is the industry terminology for gas phase filters?
What are the basic applications for gas phase filters?
Odor Control- kitchen ventilation systems, sewage treatment plants, waste storage rooms
Corrosion Control- oil and gas refineries, paper and pulp industries, data centers, microelectronics
Toxic Gas Control- oil and gas refineries
What is contact time or resident time?
Trs = Ft3 of media/Airflow (CFM) X 60
What kind of waste is activated carbon (filters)?
In case of chemical filters (in case the impurities and the chemical reaction is known), the end-user must be informed about the optional poisonous agents that may be formed on the surface.
How to eliminate carbon monoxide?
One important factor to enable the reaction is completely dried air. Humidity destroys the efficiency of the catalyst completely.
2 CO + O2 -> 2 CO2
Are all gases adsorbed in the same way?
Dependencies are related to:
Size of the molecule
Geometry of the molecule
Dependency on environmental conditions like relative humidity, air pressure and temperature.
How is it possible to measure that a filter is “full”?
In case, no detailed information about the gas loadings in the process air are known, no exact specification can be agreed upon. In those cases, a recommendation can be given to the client based on lab measurement on periodic samples, combined with an option that the carbon or chemical filter may have to be changed earlier. A simple method of detection to predict the lifetime of the filters doesn't exist.
