Company context
Our client specializes in manufacturing chemical products for injection, extrusion, or blow molding for the automotive and transportation markets. The company is also active in the electronics, electrical, construction, and industrial equipment sectors. Its products are likewise used in the food industry, perfumery, and life sciences.
Filtration challenge
The site’s Energy/Utilities Manager informed us of ongoing supply difficulties for air filters with their current supplier. This supplier, an industrial equipment manufacturer, includes air-filtration consumables as part of its service offering.
Our client questioned the supplier’s pricing practices and also expressed dissatisfaction with the delivery lead times.
Pemflow filtration challenge
Our first step in this type of situation is to list all machines equipped with air filters in order to establish a complete inventory. The second step is to identify the brands and references of the consumables. Finally, we analyze the different operating modes of the systems with the goal of either proposing an equivalent solution or considering improvement options.
The first issue to address for our client was the identification and proposal of final compressor filters. We recommended installing fine filters with F9 efficiency.
Key point
Fine filters (efficiencies M5, M6, F7, F8, and F9): Their main purpose is advanced air treatment. Designated by the letters F or M in the European standard EN 779:2012, they trap contaminants larger than 0.1 µm, such as spores and bacteria.
This type of filter is one of the main solutions used in air-purification systems for compressors.
Key characteristics:
- Microglass fiber media
- Galvanized frame
- Maximum operating temperature: 120 °C
- Opacimetric efficiency: 95%
- F9 classification (EN 779:2012)
- Aluminum separator
- Two protective grids on air inlet and outlet
The second issue to address was the filtration of the primary inlet air of a burner. As this is a coarse filtration application, our proposal focused on metal-mesh filters with G2 efficiency.
Key point
Air-treatment prefilters: Used as the first stage of air treatment, they retain the largest particles. Designated by the letter G under the European standard EN 779:2012, they provide filtration down to 10 µm and, for example, stop heavy industrial dust.
- Aluminum braid media
- Galvanized frame
- Maximum operating temperature: 200 °C
- Gravimetric efficiency: 75%
- G2 classification (EN 779:2012)
- Regenerable
Our expertise in industrial filtration enabled us to meet this company’s expectations in terms of technical guidance, pricing, and procurement lead times.
