Bag Filter Specification and Identification

Sunday, February 26th, 2012

Firstly we apologise for teaching anyone out there to suck eggs, but we have had a few requests from customers asking for a technical bulletin on how to size up a multi pocket bag filter.

In the small diagram below we show you the dimensions and extra details we require when we manufacture a bag filter for the HVAC industry.

When should i change my air filter?

Tuesday, September 6th, 2011

Struggling to decide when to change your air filters?  Struggle no more with an Airclean Inclined Manometer.  This simple device can be mounted to duct work or an air handling unit across a filter section, and will give a read out showing the pressure differential across the air filter.

Inclined Manometer

An Inclined Manometer can be used to determine when an air filter should be changed.

Throughout the life of any particulate air filter (eg. panel, bag, HEPA)  its resistance to airflow will increase and this can be visually seen on an inclined manometer.  This resistance is commonly used to show the life of an air filter and determine when it should be replaced for new.  Recommended discard resistances are shown on all Airclean Data Sheets and Operation and Maintenance Instructions, which can be found in our catalogue or on our website.

By ensuring filters are changed regularly and in line with our guideline discard pressures, an efficient system with regards to both filtration and energy can be achieved.

For more information on when you should change your filters, or how to measure the resistance of an air filter when it is in service, contact the Airclean Technical Sales Team.

World Cup 2010 – Pubs and Bars are you ready for it?

Sunday, May 23rd, 2010
Sports News - February 04, 2009

With the Fifa World Cup only two weeks away, we are asking if our Pubs and Bars are ready for the surge of football fans coming through their doors.  Some basic filtration checks could help bar staff and chefs keep cool in this busy period.  Here are our top 5.

1. Check all Air Conditioning Filters

– Dirty Air Filters in Air conditioning systems can reduce cooling efficiency and air flow, resulting in hot headed staff and football fans.  Simple replacements of panel filters, or bag filters could keep the hottest of football fans cool during a penalty shootout.

2. Check Kitchen Supply Air Filters

– Kitchen Supply Air is vital to keep chefs cool during service.  Typically Kitchen Supply Filters could be G4 Pleated Panel Filters, ranging up to F6 Bag Filters.  Changing these air filters will allow maximum air intake  making sure that come full time the kitchen will run efficiently under the increased pressure.

3. Check Kitchen Extract Filters

– Kitchen Extract Filters are just as important as the supply air filters, to make sure all hot air has a path to exit the kitchen. Mesh Grease Filters , and Baffle Grease Filters in the kitchen canopy should be checked, and cleaned with a solution such as Airclean Series 500 Grease Filter Cleaning Agent, to ensure air can pass through filters freely.  Also any secondary filters such as panel filters, bag filters, and those all important Charcoal Filters should be inspected for blockages and replaced if necessary.

4. Be Prepared!

– A break down during this period of increased business could be catastrophic so make sure you have your air conditioning companies phone number on hand just in case of an emergency.  If your kitchen is likely to experience a high increase in business, maybe consider a Heated Grease Filter Cleaning Tank, or some spare air filters, to minimise down time, and keep ahead of your maintenance schedule during the World Cup.

5. And Finally – Enjoy It!

– This tournament only comes round once every four years, and is one of the few sporting events that brings England together.  So if you are stuck behind a bar or in a kitchen, make sure you keep one eye on the score, and stay ahead of the game, and enjoy the tournament with your friend and colleagues.

If your bar or pub needs replacement kitchen filters or air conditioning filters ASAP before the world cup, contact our sales team and we will be more than happy to help!

HVAC Bag Filters – Selection and Identification

Bag Filters - High Performance HVAC

Bag Filters - High Performance Selection

High Efficiency Bag Filters are designed and manufactured to offer a high level of air quality in heating, ventilation and air conditioning systems.  These bag filters are most commonly utilised on supply air systems for swimming pools, offices, hospitals and hotels, filtering fine dust particles, carbon blacks, mould spores and airborne bacteria.

Airclean’s HVAC Multi Pocket Bag Filters are manufactured from Synthetic Medias with a high dust holding capacity offered by continuously welded pocket spacers ensuring even bag inflation.  The pockets are supported and held in place by a welded wire frame, surrounded by a galvanised steel header frame for easy installation.

When making a selection for a High Performance Bag filter rated air flows must be closely considered, as an “Under Aired” Bag Filter will not inflate correctly resulting in excessive resistance and poor filtration.  Rated air flows for Airclean’s Bag Filters are available on the main website for all standard air filters, however if a non standard size is required the technical team are on hand to offer you support.

Iceland Volcano Ash and Air Conditioning

Monday, April 19th, 2010
Smoke and lava are seen as a volcano erupts in Eyjafjallajokul

The recent eruption of the Eyjafjallajokull Volcano in Iceland has left aircraft grounded across Europe over fears that particulates in the ash cloud could damage aircraft engines.  As increasing evidence is found of this ash now falling to earth, the World Health Organisation has now warned people with breathing difficulties to remain indoors.

Over the last few days we have now received concerns from customers who are worried about their air movement equipment in offices, data centres,  and leisure complexes.   If there is an increase in airbourne particulates it is likely that they will be drawn into air conditioning systems and could pose issues for coils, fans, heat recovery heat transfers, and other fragile components.

Most Supply Air Systems have two levels of filtration ensuring a breathable quality of air is achieved.  Pre filters such as G3 Glass Panels filters, or G4 Pleated Panel Filters are used to remove large particulates, and secondary filtration is commonly acheived by High Performance Bag Filters, which remove finer particulates.

The majority of any airborne ash particulate being drawn into an air supply system should be captured by the pre filters with any residual particles being collected by the secondary filters.  If there is a significant increase in airborne particulate, air filter life could drastically reduce resulting in loss of airflow, or additional strain on the fan resulting in reduced energy efficiency.

To our clients we advising not to be too concerned at present, but should the volcanic eruption continue for a significant period of time, or if the evidence of falling ash particles continues to increase, you may need to make a filter change sooner than your regular maintenance. To be able to monitor filter performance you may find fitting  a magnehelic guage or an inclined manometer may help.
