Nestro to focus on Energy efficiency and noise reduction at LIGNA

02In the year of its 40th anniversary, NESTRO® Lufttechnik GmbH is presenting itself on a base area of 192 m² in hall 15 / G69with a two-level exhibition stand for the first time. The company is exhibiting its Filter technology and surface engineering solutions, mainly in live operation, and looks forward to once again providing extraction for all processing machines in the “HOMAG City”.

NESTRO® offers self-contained system solutions and considers itself a market leader for the fields of Dust, chip and spray mist extraction in woodworking / the wood industry. The company rises to the growing challenges of energy efficiency and noise reduction with competent, comprehensive consulting services and suitable technology. Considerable energy savings can be realised on the system side by using highly efficient fans, frequency converters for fan control, high efficiency motors (IE3, IE4) and recirculating air instead of exhaust air systems, as well as by using the return air for heating or air conditioning. Subsidies are available in some countries that make even the retrofitting of existing systems interesting – for example to change raw gas into clean gas systems. Noise emissions can also be drastically reduced through optimum product and system design as well as various insulation measures. With NESTRO®, trade fair visitors have the opportunity to experience and evaluate many applications in live operation.

NE 200 deduster    
An NE 200 is extracting dust and chips live from a panel-sizing saw in the “HOMAG City”. Since all NESTRO® dedusters work in clean gas operation – the fan comes after the filter –highest energy efficiencies and absolute dust tightness are guaranteed. The clean gas technology also reduces the risk of fire due to sparks since metal particles cannot get to the fan impeller. Operation with a maximum sound pressure level of 72 dB (A) is “whisper quiet” (open-air noise level according to the machinery directive with a distance of 1.0 m at a height of 1.6 m; measurement according to EN-ISO 11201, measured with nominal flow rate, without material conveyance). The residual dust content in the air discharged into the exhibition hall is less than 0.1 mg/m³.
NE 350 deduster
The NESTRO® NE 350 deduster with an operating volume flow of 9,500 m³/h is the successful product family’s power pack. It has nominal volume flow of 6,927 m³/h with corresponding negative pressure of 2,750 Pascal, making it predestined for the extraction of CNC machines with high-speed processing or larger standard trains of machines in the wood industry where the simultaneous operation of various machines demands a high air volume. The BG-certified deduster can be set up in the immediate vicinity of the machine in the production hall and can also be used for filtering related materials such as plastic, leather, paper or other types of industrial dust.

NFHSU 11/11-35 filter house with NBP C160   
The NESTRO® cleangas filter house allows large filter areas to fit in the tightest of spaces and material accumulated through the day to be stored temporarily. This system features a filter area of 305 m² and two fans for an air volume of 13,000 m³/h each.It allows visitors to experience live how wood chips and wood dust are filtered, collected and processed into briquettes with a diameter of 60 mm. Material is supplied to the filter house from the extraction of numerous HOMAG processing machines through duct 1 and from a chipper at the own exhibition stand.

Intermediate filter 9/4-30 with use of return air    
A NESTRO® intermediate filter 9/4-30 with a construction height of more than 8 m is set up outside the western façade of hall 15. It provides extraction for additional HOMAG processing machines through the second duct. This filter well exemplifies the modular design with individual add-on elements. In practice the extraction performance can be freely chosen from 4,000 to 150,000 m³/h according to individual customer requirements. The 9/4-30 design used here has a filter area of 77 m² in each element. Three fans generate a flow rate of up to 45,000 m³/h. The outstanding visual quality of the filter is achieved thanks to its smooth surface due to consistent inside bending so typical for NESTRO®. Return air is discharged back into the exhibition hall, reducing the load on the air conditioning system and effectively improving the air quality (residual dust content

NZL 4 chipper  
NESTRO® shredders convert your disposal costs into energy gains – very quietly. With the NZL 4, the offset arrangement of the turning plates ensures low energy consumption while the low speed guarantees quiet operation. All wearing parts are designed to be very robust with a long lifespan. Large viewing windows allow visitors to clearly observe the always impressive chipping of the material (hardwood, softwood and chipboard) between the rotating knives on the rotor shaft and the fixed bed knife in the machine bed.

NST 95 grinding bench for grinding dust – NEW  

 
The NESTRO® NST 95 grinding bench with an air volume of 9,500 m³/h is the big brother of the successful NST 75 and removes dust from a 5400×3100 mm work surface with a separation rate of up to 95%. This ensures maximum freedom of movement, even with really large work pieces. Trade fair visitors can see for themselves how grinding dust is effectively bound in the easy to clean filter elements by means of a low-turbulence directed airflow. Recirculating air operation reduces energy costs for the user and ensures a pleasant room atmosphere with minimal drafts in full compliance with the workplace directive.

NAST 24 grinding table for grinding dust – NEW
The NESTRO® NAST 24 grinding table with a 2000 x 1000 mm work surface closes the gap between the two established sizes, 16 and 28. Ithas now been added to the standard program in response to numerous customer requests. Hydraulic table height adjustment, the pneumatic component clamping fixture that makes work much easier and the high-pressure extraction port for manual machine extraction and cleaning are included in the accessories for all grinding tables.

PAINTLINE system for spray mist 
NESTRO® offers the PAINTLINE system in three performance classes with flow rates between 7,500 and 24,500 m³/h for the highest coating demands. The company is giving a live demonstration of medium performance class spray mist extraction at its exhibition stand. As solvents and paints sink to the ground due to their greater density, the paint particles are suctioned up in a continuous, low-draught air flow near the floor and then bound in the filter mats. The PAINTLINE systems allow a paint finish of consistently high quality even in continuous operation with extremely easy handling. NESTRO® custom-designs each of these systems based on the requirements of the customer and the space available. The individual systems are also scalable on demand thanks to the modular design.
