Durum: yeni, Üretim yılı: 2026, Fonksiyonellik: tamamen fonksiyonel, CORMAK LUFT 1000 VSD+PM Compact Rotary Screw Compressor with Dryer – Compact Set for Demanding Applications – ENERGY SAVER SET INCLUDES: - LUFT 1000 VSD+PM COMPACT rotary screw compressor with integrated dryer. - 500 L horizontal compressed air receiver. Key features that distinguish these models: 1. Permanent Magnet Motor (PM) Technology Most compressors in the Energy Saver series utilize Permanent Magnet motors. Compared to standard induction motors: Bsdpfxeycg Ufj Ac Iodd - Achieve efficiency levels corresponding to IE4 or even IE5 standards. - Maintain high performance even at very low RPMs (where standard motors lose efficiency outside their nominal range). - These motors are more compact, lighter, and generate less heat. 2. Advanced Variable Speed Drive (VSD) Control At the heart of the Energy Saver range is the frequency inverter (VSD). - Needs-based adaptation: The compressor does not operate on a simple load/unload binary cycle. If your machine requires only 30% capacity, the compressor reduces its speed accordingly, consuming proportionally less energy. - Elimination of idle running: Traditional compressors often continue running for several minutes after filling the tank, consuming about 25–30% of the rated power without producing air. Energy Saver models virtually eliminate this wasteful process. 3. Soft Start Function Thanks to the VSD, these machines start smoothly from 0 Hz. This means no abrupt current surges during startup, which: - Spares the facility’s electrical installation. - Allows for frequent starting and stopping without risk of winding overheating. 4. Genuine Energy Savings In practice, implementing the Energy Saver lineup can reduce electricity bills by 30% to 50% compared to traditional fixed-speed compressors. Additionally, the system maintains highly stable network pressure (accurate to 0.1 bar), which is crucial for precision equipment such as laser cutters. Extended service life: Absence of rapid pressure and temperature spikes prolongs the life of the screw element. Technical Specifications Motor power: 7.5 kW / 11 HP Voltage: 400V/50Hz Output at 0-6 bar: average 990 L/min Output at 6 bar: 990 L/min Output at 8 bar: 950 L/min Output at 10 bar: 950 L/min Outlet connection diameter (G): 3/4" Dimensions: 1495 x 600 x 1600 mm Weight: 350 kg

Durum: yeni, Üretim yılı: 2026, CORMAK LUFT 1500 VSD+PM Compact Rotary Screw Compressor with Dryer – Compact Set for Demanding Applications – ENERGY SAVER Bdsdpfx Acsychbae Ied SET INCLUDES: LUFT 1500 VSD+PM COMPACT rotary screw compressor with integrated dryer. 500 L horizontal compressed air receiver. Key features distinguishing these models: 1. Permanent Magnet Motor Technology (PM) Most compressors from the Energy Saver series utilize Permanent Magnet motors. Compared to standard induction motors: They offer efficiency levels meeting IE4 or even IE5 standards. Maintain high performance even at very low speeds (where standard motors lose efficiency outside their nominal range). Are smaller, lighter, and generate less heat. 2. Advanced Inverter (VSD) Control At the core of the Energy Saver line is a frequency converter (inverter). Demand-driven operation: The compressor does not operate in an all-or-nothing (load/unload) mode. When your equipment requires only 30% capacity, the compressor reduces RPM accordingly, consuming proportionally less energy. Elimination of idle running: Traditional compressors often run for several minutes after the tank is filled, consuming approx. 25–30% of nominal power without producing air. Energy Saver models almost completely eliminate this wasteful process. 3. Soft Start Thanks to the inverter, these units start smoothly from 0 Hz. This means there are no sudden current surges during startup, which: Protects the facility’s electrical installation. Allows more frequent start/stop cycles without risk of motor winding overheating. 4. Tangible Cost Savings In practice, using the Energy Saver line enables reducing electricity bills by 30% to 50% compared to traditional fixed-speed compressors. The system also maintains highly stable network pressure (accurate to 0.1 bar), which is crucial for precision machinery such as laser cutters. Extended service life: The elimination of sudden pressure and temperature spikes increases the lifetime of the screw assembly. Technical specifications Motor power: 11 kW / 15 HP Voltage: 400V/50Hz Capacity 0–6 bar: 1620 L/min Capacity at 6 bar: 1580 L/min Capacity at 8 bar: 1350 L/min Capacity at 10 bar: 1230 L/min Discharge port diameter (G): 1" Dimensions: 1600 x 740 x 1750 mm Weight: 500 kg

Durum: yeni, Üretim yılı: 2026, CORMAK LUFT 700 VSD+PM Compact Screw Compressor with Dryer – Compact Set for Demanding Applications - ENERGY SAVER SET INCLUDES: - LUFT 700 VSD+PM COMPACT screw compressor with integrated dryer. - 500 L horizontal compressed air receiver. Key features that distinguish these models: 1. Permanent Magnet Motor Technology (PM) Most Energy Saver series compressors utilize Permanent Magnet motors. Unlike standard induction motors: - They achieve efficiency levels in line with IE4 or even IE5 standards. - Maintain high efficiency even at very low speeds (where standard motors lose efficiency outside their nominal range). - Are smaller, lighter, and generate less heat. 2. Advanced Variable Speed Drive Control (VSD) The core of the Energy Saver line is the frequency inverter (VSD). - Demand-driven: The compressor doesn't operate on a simple on/off (load/unload) system. If your machine only needs 30% of the capacity, the compressor reduces speed and consumes proportionally less energy. - Eliminates idling losses: Traditional compressors often run for several minutes after filling the receiver, consuming about 25–30% of nominal power while not producing air. Energy Saver models almost completely eliminate this wasteful process. 3. Soft Start Thanks to the inverter, these units start smoothly from 0 Hz. This means no sudden current spikes at startup, which: Bdsdsycg Ryopfx Ac Ijd - Protects the facility’s electrical installation. - Allows more frequent startups and stops without risk of winding overheating. 4. Real Savings In practice, using the Energy Saver line can reduce electricity bills by 30% to 50% compared to conventional fixed-speed compressors. Additionally, the system maintains a very stable network pressure (accuracy to 0.1 bar), which is crucial for precision devices like laser cutters. Longer lifespan: The absence of sudden pressure and temperature surges extends the screw stage’s service life.

Accumulated chips, burnt adhesive residues, and other foreign objects negatively affect a consistently thin glue application. This applies when using EVA hot-melt adhesives, and especially for the use of PUR adhesives. If the glue pot remains in the machine, poor accessibility limits cleaning effectiveness. If the unit is removed—which is quick and easy with most brands—rapid cooling prevents thorough cleaning. Additionally, there is usually no stable holder for the still-hot glue pot, nor a drive for the glue roller. With this easy-to-use device, regular cleaning and maintenance tasks can be easily performed by operating or maintenance personnel themselves.
