Filters made at our factory in Nantes (France) Standard Filtr’Overspray is well adapted to filtration of paint overspray in spray booths. It is easy to manipulate and to stock. Its lifetime, 6 times longer than other filtering medias on the market, allows to make important costs reductions. This filter is perfectly adapted to filtration of any wet overspray particles (paints, varnishes, gel coat, glue, silicone, polyester etc…) Advantages of this filter : - Lifetime up to 6 times longer than other filtering medias on the market - Easy installation and manipulation - Environment friendly materials according to ISO 14000 - Adapted to filtration of solvent paints and water based paints This filter can be used in all spray booth with horizontal and vertical airflow.

Filters made at our factory in Nantes (France) This filter uses the same principle than Standard Pleated Cardboard Filter with a polyester media sticked at the back in order to increase filtration efficiency for dry dusts. Advantages of this filter : - Lifetime up to 3-4 times longer than other filtering medias on the market - Better filtration efficiency than Standard Pleated Cardboard Filter - Easy installation and manipulation This filter can be used in all spray booths with horizontal and vertical airflow. Construction : This filter is made of 2 layers of recycled kraft paper, perforated, pleated and glued with a polyester media at the back. The quality of kraft paper (250g/m²) guaranties rigidity of the filter in all positions. Standard widths : - 1m - 0,90m - 0,75m Other dimensions and cuts on demand.

The Exofalc Choquenet candle filter is used in many industries such as the food industry (sugar refinery, cocoa, etc.), chemicals, alumina, pharmaceuticals, etc. Indeed, its simplicity of use (100% automatic) combined with a technology allowing a high concentration of sludge makes it a formidable thickening filter adaptable to many fields. It offers high filtration rates/filtering surface ratios for a modest footprint. A permanent visual control of the quality of the filtrate allows to react instantly in case of a punctured or clogged cloth, each ramp being individual, it can be isolated in order to maintain a high production rate. It also has the advantage of being able to see its internal filtering surface evolve according to customer constraints without modifying its external environment. Finally, due to its design and degree of automation, it allows increased productivity with very low operating costs.

The environmental protection has become essential. The water quality is a rare and expensive commodity and its production involves a problem more and more present with the industrial or urban slurries which need to be eliminated at a lower cost and if possible to be recovered. The filter-press has an important place in numerous industries whenever slurries can be concentrated : it can be used either in process or at the end of treatment. In any case the filter-press enables an optimal separation of liquid and solid and the last technical developments which has made it 100 % automatic made it also 100 % topical. The filter-presse is a machine used to filter under pressure the liquids loaded with solid matter in suspension. The filter-press is composed of 3 main parts : the frame, the filter part and the hydraulic power unit..

This equipment was developed some years ago in food processing industry. Its qualities in thickening as well as in clarifying involved the present use of this equipment in a lot of industries. It replaces now the decanters with numerous advantages : Reduced space on the floor Much better turbidity of filtered liquids Very efficient thickening Specificity of the EXOFALC filter The filter cloth is perfectly adapted to the candle size ; the low amplitude with respect to its support avoids its deformation. 

The filtered juices are not in opposition when they are removed what conferes to the candle a specific large flowrate and a juice turbidity which becomes rapidly better than with a frame filter with outlets in opposition. EXOFALC filter performances Specific flowrate (depending on the slurry) from 1 to 2.5 m³/m²/hr Slurry concentration : from 160 gr/l to 540 gr/l depending on application

CHOQUENET provides its customers with mobile units to confirm feasibility on site The company provides several mobile filtration units of different sizes (from the laboratory unit of 250 cm² filtering surface to the semi-industrial installation of 9 m²). These units make it possible to test many parameters in an easy way. Rental can be on a one-off basis (for a week or less) or on a more permanent basis (up to several months for specific production needs).

CHOQUENET provides its customers with mobile units to confirm feasibility on site The company provides several mobile filtration units of different sizes (from a laboratory unit with a 50 cm² filtering surface to a 40 m² installation). These units allow us to carry out feasibility tests over a short period of time and also to confirm the various choices of technology (trays and frames, choice of cloths, necessary cycles, etc.). Rental can be on a one-off basis (for a week or less) or on a more permanent basis (up to several months for specific production needs).

For short or long term filtration, the CHOQUENET mobile filter is THE solution for your dehydration missions. The European industry has to be as reactive and flexible as possible in order to face its international competitors. In order to support our many partners in this process, we have developed filter presses that can be installed and commissioned in less than 24 hours. The entire machine and its accessories are housed in a 3-axle trailer that can be moved according to the customer’s needs.

Reduction of our CO2 emissions Choquenet has now set up an operating process exclusively dedicated to the circular economy of its machines. Remanufacturing We are now able to remanufacture used filters to give them a new lease of life and allow them to live new adventures in an identical or different industrial environment. By actively participating in the preservation of our planet, the interests of such a solution are multiple for our customers. The history and experience acquired during the first life of the machine allows us to propose ergonomic, technical and economic improvements to the machine. Our customers thus benefit from used equipment with the same or even higher level of performance and quality than the original, at a lower cost than a new investment.

Innovative eco-friendly filtration Makes it possible to dehydrate products that are difficult to filter by combining pressure filtration with the application of an electric field. This technology avoids the addition of additives that could contaminate the final product. This application allows in particular to : – Reduce the filtration time – Increase the quality of the dehydration – Reduce energy consumption compared to thermal dewatering This equipment can be adapted to existing machines. 4 areas of application today that can be filtered: Sludge containing hydrocarbons, drilling mud, spa sludge and fish farming sludge 75% of dryness obtained 100% reduction of reagents Eco-design: Reduced environmental impact by optimising the design of the equipment
