About local exhaust ventilation

What is Local exhaust ventilation?

Local exhaust ventilation is a proven and cost effective means of removing airborne fume and dust hazards from the workplace to ensure operator safety and comfort.

How do the systems work?

Potentially harmful fumes are captured at source and passed through a series of filters which remove hazardous particulate and gases before recirculating the cleaned air back into the workplace.

Which extraction system do I need for my application?

PURE-AIR has a range of extraction systems suitable for a wide range of applications across several industries.

Please refer to Your industry in the first instance. In here, our search function will help you identify suitable units and our product comparison tool will help you work out what is right for you.

If you are still unsure which is the right system for you, our technical engineers can work with you to understand your process and establish which system and filters are compatible. Contact us for more information.


Where can I get a user manual for my extraction system?

All machines are dispatched with a user manual book.

If you no longer have this, you can access our user manuals by logging into our customer portal. If you don't have login details, please complete the customer sign up form and we'll get back to you shortly.

What flow rate (speed) should my machine be set to? (If unit fitted with variable speed control)

You can find the unit model on the silver label attached to the unit - you can find this on the side or the rear of the unit.

We recommend setting the extraction rate as low as possible but so that the fume can still be effectively removed from enclosures/breathing zones.

Can my extractor connect to my process machine for automatic control?

This preserves the life of filters and internal components of the extractor.

There are a number of optional extras available for our extractors, including interface cables which allows extractors to communicate with PLC's or machines to show filter status or allow a remote stop/start.

For more information please liaise with your sales representative.


How often should I replace my filters?

The frequency with which you need to change your filter will be determined by the specific application you are using your fume extraction systems for. The following should be treated as guidelines only:

We recommend that filters 'in use' are replaced every 12 months (both pre and combined or bag/HEPA).

Otherwise, please replace when filter indication screen or LED lights state a blockage.

Please note, this is a guide only as each filter will depend on the specific application it is being applied to.

How do I change my filters?

Please refer to your user manual for guidance on how to change the filter in you specific unit. Alternatively login to our customer portal to access short, easy to follow videos showing you exactly how to replace your filter.

How can I buy a new filter?

Please contact the company you bought your extraction unit from.

If you bought your system directly from PURE-AIR, please complete our contact form.

Do PURE-AIR offer a service to take away old / saturated filters?

PURE-AIR does not dispose of customer's filters as we cannot guarantee the history of used or saturated filters and so we may be putting the health of our staff or the disposal companies at risk.

How do I know what filters my unit takes?

Every PURE-AIR filter has description located on a yellow label attached to the filter.

If the label is missing, please contact the PURE-AIR sales or technical department and quote the unit's model and serial number.

My extractor LCD/LED filter condition display states my filters are in good condition, however I can smell the process - why?

Filter condition displays only register a physical blockage so will not alert you to a saturated carbon filter (unless the VOC sensor option is fitted to the machine). Any smell coming from the extraction unit's exhaust is a strong indication that either the extraction is not adequate enough to contain the contaminant release or the carbon in the filter has become saturated and requires replacement.

For further assistance, please contact PURE-AIR asap, providing as much detail as you can about your application.
