B. Enclosed as sold, class not stated or stated as Class 4
| Model | Type / power | Work area (mm) | Class statement | Passthrough / exhaust as stated | Confidence |
|---|---|---|---|---|---|
| Glowforge Pro | CO2 45 W | 495 × 279 | "The Glowforge Pro is a Class 4 laser device and comes with all necessary safety training materials" | "Pro Passthrough slot … up to 1/4″ (6.3mm) high" | high — not a Class 1 machine per manufacturer |

Not in either list — enclosure not stated verbatim: Gweike Cloud 50W Pro II (JSON states "1. Built-in Water Chiller, ≤70dB 2. Air Exhaust Fan, ≤70dB 3. Built-in Air Compressor, ≤70dB" but not the word "enclosed").

Four specs that matter in a small room
- Stated class. Five rows carry a manufacturer Class 1 statement (list A). The Glowforge Pro carries a Class 4 statement from its manufacturer and is therefore listed in B, not A. An empty cell means "not stated", not "unsafe"; we do not infer a class from an enclosure. Definitions: FDA 21 CFR 1040.10; IEC 60825-1 (published by the IEC, iec.ch).
- Exhaust. Stated verbatim only by OMTech ("Air Flow: 282 cfm (480 m³/h)"), Gweike ("Air Exhaust Fan, ≤70dB") and Glowforge ("Ventilation with either the Glowforge Compact Filter, or an open-able window within 8 feet"). For every other model the duct or filter arrangement must be read on the manufacturer's accessory pages; we make no statement about indoor air quality.
- Footprint. Stated for Glowforge ("38″ x 20.75″ x 8.25″ (965mm x 527mm x 210mm)") and OMTech (package 1180 × 650 × 375 mm);
footprint_mmfield planned for all rows. - Passthrough. An enclosed machine with a passthrough slot (S1, OMTech Polar Lite, Glowforge Pro, Spark) has an opening by design. How each manufacturer treats class with the slot is for the manufacturer's text, quoted where it exists (Glowforge: Pro = Class 4; the fetched OMTech and xTool pages do not state a class).
Material note
Several manufacturers publish lists of materials not to process. This site will quote those lists per model on the spec sheets, with the source, and will not add its own list.
Questions
Does "enclosed" mean "Class 1"?
No. Glowforge sells the Pro enclosed and states Class 4 for it. "Class 1" appears on this site only where the manufacturer states it, quoted.
Which enclosed units state a passthrough?
xTool S1 ("AutoPassthrough™"), OMTech Polar Lite ("Front & Rear Pass-Through: 15.8 x 0.3 in. (400×7 mm)"), Glowforge Pro (slot), Glowforge Spark (overview table).
Which has the largest stated work area among enclosed units?
Creality Falcon2 Pro, 400 × 400 mm = 160,000 mm²; then xTool S1 40W, 498 × 319 = 158,862 mm²; then OMTech Polar Lite, 510 × 300 = 153,000 mm² (our arithmetic from stated dimensions).
