Halward has a range of Purifiers with and without CO / CO2 reduction to offer breathing air quality as per International Breathing Air Standards.

Employers are advised by health and safety legislation to provide Respiratory Protective Equipment (RPE) in addition to Personal Protective Equipment (PPE) wherever there is the possibility of employees or site visitors inhaling hazardous substances.

Typical Hazardous Substances

 Biological agents – bacteria and other microorganisms

• Dusts – with high concentration levels (produced during

grinding, sanding or milling)

• Noble gases – e.g. argon and helium (not directly

hazardous but can cause oxygen deficiency)

• Processed substances – such as pesticides, medicines

chemicals and cosmetics

• Fumes – often created during welding, smelting

and pouring molten metals

• Mists – liquid droplets formed by atomization and

condensation processes. Mists can be created by

plating, spraying, mixing and cleaning operations

• Asbestos – used extensively in buildings from the

1940’s to 1960’s. Exposure to asbestos fibers can cause

asbestosis, lung cancer or mesothelioma

• Lead poisoning – lead poisoning is likely to build

up slowly over time and can pose serious risks

including, brain, nerve and kidney damage

Halward has a a range of Purificaton Devices to maintain the desired quality of Compressed  well below the designated Osha Grade D or European Pharmacopoela norms.

We are offering Range of Compressed Air  and Gas Filters to our clients.

Coalescing Filter (Pre-Filter) Elements:

• Coalescing filters capture oil, moisture and particles, binding them together until their mass is heavy enough for gravity to send this waste to a drain valve. A coalescer filter is often called a pre-filter because it is usually located prior to an air dryer to prevent oil and particulate from soiling the desiccant.

Particulate Filter (After-Filter) Elements:

• A particulate filter, also known as an after-filter, is usually located just after the desiccant air dryer to capture any fine desiccant particles that may be in the line. If the particulate filter gets soiled more frequently than what is typical for your environment, it may be time to replace the desiccant.

Adsorber Filter Elements:

• Adsorbers remove odor from process air and are usually located on the air line after the dryer. Adsorption filters with activated carbon are for adsorption of harmful gases and smells from the air. The largest use of Carbon elements is in the purification of water. Activated carbon achieves the maximum enlargement of inner and outer surface after the special treatment and so the adsorption area is extremely high - up to 1250 m2 for every gram of active carbon.

We manufacture and supply the following type of air filters in commercial and Industrial HVAC systems:

Fiberglass filter. This throwaway air filter is the most common type. Layered fiberglass fibers are laid over each other to form the filter media and typically are reinforced with a metal grating that supports the fiberglass to prevent failure and collapse.

Polyester and pleated filters. These filters are similar to fiberglass filters but typically have a higher resistance to airflow and a superior dust-stopping ability.

High efficiency particulate arrestance (HEPA) filters. These units filter the air passing through them at a very fine scale. Specification for HEPA Filters Used by pharmacutical and process Industries is to filter 99.97 percent of all particles 0.3 microns or larger.

Washable air filters. These products are not as common and rely on the build-up of dust along the cloth to improve the efficiency of the filter. Industrial processes involving high volumes of coarse dust are typical applications.
