Reliable and professional parts replacement & products service system makes it a longer service life LT-80W-AA-PRO-KIT: 【Powerful Laser Engraving and Cutting】 With 80W machine power and 10W optical laser power output, this laser module can engrave 304 stainless steel up to 300mm/s and cut through 8mm thick plywood, 15mm pinewood, and 5mm thick dark acrylic in one pass. Dual compressed spot enables finer laser engraving at 0.08*0.08mmm 【Upgraded Laser Module for Better Performance】 The blue light laser module has been upgraded with a 6mm diameter bending air metal nozzle that reduces air resistance, resulting in faster, deeper, and smoother cutting with fewer burn marks. The magnetically attached laser shield filters 97% of UV rays to protect your eyes and those around you. The top of the laser module adds fan protection and an air tube holder 2-in-1 stainless steel piece. 【Wide Compatibility with Other Machines】 This laser engraver module is compatible with PWM-controlled DIY machines, laser cutter machines, CNC routers, and 3D printer machines. It has a multi-hole position on the back, making it easy to install on different laser cutting and engraving machine stands. The adapter board is compatible with different voltages and pins between the machine and the module. 【Ultra-Fine Laser Head with FAC】 The diodes Laser module has an original diode with high stability, efficiency, and quality, with a lifetime of 20,000 hours. The built-in FAC makes the beam size much smaller at focus (0.08*0.08), resulting in super cutting penetration and precision. The power density increases 4~5 times, and the engraving speed increases 4~5 times accordingly. The precision also increases 4~5 times, allowing you to directly engrave smooth stainless steel metal and ceramics. 【Technical Support and After Service】 The laser engraver module KIT package includes 1* Laser module; 1* Driver adapter; 1*Eye protection cover; 1*Spare protective window glass; 1*3 Pin input cable; 1* L Wrench; 3*Focus fixing plate. Choose the 12V or 24V module according to the DC of your machine driver board. If you have any questions, visit eBay or the website and get professional technical support in time. LT-AP-110V/220V: Large Airflow Air Assist Pump: LASER TREE Air Pump equipped with adjustable airflow of 0-30L/min. Large and steady output airflow can blow away the smoke and dust generated during laser cutting. Prevent smoke and dust from attenuating laser energy, and increase the lifespan of the laser module lens. Help cut faster cleaner and deeper. Get Clean Surface and Smooth Edge: Powerful air assist pump's airflow quickly reduces the surface temperature of cutting objects, preventing distortion and discoloration due to excessive burning and making the cutting edge smoother and cleaner. Wide Compatibility: The Laser air pump kit is equipped with two sizes of nozzles (PC6-M8 & PC8-M8)and hoses( φ8x6mm & φ6x4mm), compatible with most of the laser cutter and laser engraver machine’s nozzle interfaces on the market. If it is a special size module air inlet nozzle just needs to replace the appropriate air tube and air outlet nozzle. Plug and Play. Durable & Stable: This air pump is made of a high-quality aluminum shell, which is easy to maintain. It is fully compatible with the LASER TREE laser module. There are 4 rubber feet to reduce noise and vibration in operation. High stability design to maintain stable airflow output even after a long working time.
