The NASAN NA-B2+ Pro sits at the center of a screen refurbishing bench because it merges two separate machines into one footprint, and that single change reshapes how a repair shop moves glass through the workflow. Screen refurbishing runs on two stages that used to demand two machines: separating the old glass from a frame or LCD, then laminating a new glass and removing the trapped air bubbles from the OCA layer before the panel ships out. The NA-B2+ Pro handles both stages on the same 7-inch platform, so a technician moves a panel from separation straight into the autoclave chamber without walking it across the shop. You control the whole cycle from a touch panel that sets temperature, timing, and air pressure directly, rather than relying on mechanical dials that drift out of calibration after months of daily use. Air pressure adjusts across a 0 to 0.8 MPa range, which covers the pressure window most OCA adhesives and lamination films need to seal flat without crushing the digitizer underneath. A built-in air compressor removes the need to plumb the machine into a separate compressor line, though the unit still accepts an external compressor if your shop already runs one for other tools, giving you flexibility either way. The same build carries an integrated vacuum pump for the separation side, so lifting a cracked glass off a frame or peeling a digitizer away from an LCD backlight happens on the same chassis that runs the bubble removal cycle. For a shop doing volume screen repair, that dual function changes the layout of the whole repair bench: one machine covers the separation step for old panels coming in and the defoaming step for new panels going out, instead of routing jobs between two stations. Bubble removal on the NA-B2+ Pro runs fast, with cycles landing around 30 seconds per piece once the chamber reaches operating pressure and temperature, which keeps throughput high during busy screen replacement runs. The autoclave function pulls trapped air out of the OCA layer between the glass and the LCD, which is the step that decides whether a laminated screen ships out clear or comes back with visible bubbles and black spots under the glass. Skipping or rushing this step is one of the most common reasons refurbished screens fail quality checks, so a dedicated autoclave with real pressure and temperature control earns its place on the bench even in shops that already own a basic hot press. The 7-inch work area covers the vast majority of phone screens on the market along with small tablets, spanning current and older-generation iPhone panels, Samsung AMOLED and OLED assemblies, and the wide range of Android glass from Huawei, Xiaomi, Oppo, Vivo, and other brands that use standard OCA lamination in their repair supply chains. Because the chamber handles LCD, LED, and OLED substrates without separate settings for each panel type, the same machine covers a shop's full incoming mix rather than forcing a second unit for a specific screen technology. Voltage runs on a 110V/220V selectable input, so the unit adapts to local mains power without a separate step-down transformer, which matters for shops running multiple machines off shared circuits. The touch panel interface is worth calling out on its own, since older-generation bubble removers relied on analog pressure gauges and manual timers that made repeatable results dependent on operator experience. Setting exact pressure and timing on a digital panel means a junior technician gets the same output as a senior technician running the same job, which matters when quality control across a repair team is inconsistent. For a shop separating and relaminating screens as part of a glass-only repair service, rather than replacing full LCD assemblies, the NA-B2+ Pro directly supports that revenue model: separate the cracked outer glass, laminate a new glass panel with OCA film, run the autoclave cycle to clear bubbles, and return a screen that looks factory-fresh at a fraction of the cost of a full LCD replacement. That workflow only holds together if the separator and the autoclave sit close together and share consistent settings, which is exactly what the 2-in-1 design solves. Built-in compressor and pump also reduce points of failure on the bench, since fewer external hoses and standalone compressors mean fewer leaks and fewer maintenance calls over the life of the machine. For a technical training institute or a growing repair shop weighing whether to buy a separator and an autoclave separately or invest in a combined unit, the NA-B2+ Pro removes that decision by covering both functions from day one, at a footprint and price point that fits a single-station setup.
