Spot bag filters NS

Return the product back to technology – reduce its losses.

The TAMA AERNOVA company has been producing and installing bag aspiration filters for more than 35 years – the reliability of the S series filter line has been proven over years of successful operation in various technological processes, from the food to the metallurgical and chemical industries.


TAMA filters are the result of 30 years of work by engineers who constantly improved the filter design to meet customer needs and integrated components of the highest quality. Best in class – with customer care, thought out to the smallest detail.

An innovative approach to air flow

Thanks to the airflow simulations used in the development of the NS point bag filter, we can ensure efficient dust capture in the process.

Advanced filter materials, classic cartridge shape

High quality filter elements filter all types of dust with 99.99% efficiency, providing filtration levels that meet regulatory emission limits for most dust types.

Regeneration of filter elements

The filter element regeneration system has a classic design - cleaning with pulses of compressed air. The filter is equipped with Venturi tubes that ensure uniform, 50% more efficient, cleaning of the filter elements. This allows the filter to work longer and more consistently before replacing the filter elements.


To enable continuous operation in the aspiration system, the filter is equipped with a differential pressure controller, which monitors the degree of contamination of the filter elements in real time and activates the regeneration system only when necessary. Thanks to this, TAMA bag filters have reduced compressed air consumption, which allows saving on electricity and also ensures more stable operating parameters of the aspiration system.


The filters can optionally be equipped with an additional EcoNet PLUS system for complete remote monitoring and control of the operation of the aspiration system. With its help, you can immediately prevent unexpected downtime, monitor important parameters and find possible malfunctions before they occur.

Ease of maintenance

Each TAMA bag filter has the ability to be serviced both through the top and side service doors, which allows for more flexibility in choosing the installation location of the filter. The service platform makes servicing the bag filter easy and completely safe.
With a limited service distance to the filter roof, it is possible to install separate filter frames, which allows you to reduce the required space for replacing filter elements by 2-3 times.

Explosion-proof version ATEX

For safe operation of the filter when filtering explosive dust, NS bag filters are supplied in an explosion-proof version:

Explosion pressure release – ATEX version of the bag filter, equipped with an explosion-proof bursting membrane, which, in the event of a dust explosion, releases excess pressure and flame.

Flame filter – additionally, the filter can be equipped with a flame arrester to filter the ejected flame, which makes it possible to release an explosion even into a room.

To reduce the likelihood of an explosion and eliminate one of the ignition sources, the ATEX version of the filter is equipped with antistatic filter elements, grounded, and all external components are Ex CAT 3D.

The listed measures allow the use of a bag filter to filter explosive dust and install it in explosive dust environments.

Modular design – compact design

TAMA bag filters are made from standardized panels and have a modular design, thanks to which we can use the NS filter in various technological processes.
