Both models share the same 3HP motor and peak CFM rating. The G-800 PRO delivers measurably higher real-world performance through its 27% larger filter, adjustable vertical intake, 150% larger fine-dust box, and more spacious internal airflow path — making it the superior long-term investment for demanding shops. The G-700 PRO delivers the same proven Gyro Air technology in a more compact, accessible package.
Selecting the right dust collector is one of the most important investments you can make for your woodworking shop. While the Harvey G-700 PRO and G-800 PRO share an identical motor, fan system, and core Gyro Air separation technology, their performance in real-world woodworking environments is not the same.


A dust collector's filter is one of the largest airflow restrictions in the system. More filter surface area means less resistance and more stable suction at the tool. The G-800 PRO has 27% more filter surface area — which is why it delivers stronger real-world suction despite having the same motor and fan.
G-700 PRO: ~750 CFM (1,275 m³/h) · G-800 PRO: ~850 CFM (1,450 m³/h) — a 14% increase in real airflow.
Less static pressure pushback · Higher sustained CFM on large tools · Less frequent filter cleaning · Better performance with fine-dust machines (drum sanders, jointers, planers).

The G-700 PRO uses a fixed side intake. The horizontal entry introduces additional turbulence as chips and dust must make a sharp turn before entering the separation chamber. The G-800 PRO features a vertical, adjustable intake that accepts dust straight down from above — delivering gravity-assisted separation, smoother airflow, fewer obstructions, better handling of large debris, reduced inlet clogging, and more stable pressure across long duct runs.

The G-700 PRO has a fixed side-mounted inlet. The G-800 PRO's adjustable inlet moves from side to top — extremely valuable for shops with overhead ducting or compact layouts. A top-mounted inlet allows shorter vertical duct runs, fewer elbows, lower static pressure loss, and cleaner duct layouts overall.
The G-800 PRO is physically larger and heavier by design — the additional space accommodates the larger filter, increased dust capacity, a more robust airflow path, and a stronger structure. At 40% more overall volume and 20% heavier (650 lbs vs 540 lbs), its larger frame supports more demanding shop conditions.
Both machines use a two-stage system. The main chip bins are comparable — the G-700 PRO's is slightly larger (33.8 gal vs 29 gal). The major difference is in the fine-dust chamber: the G-800 PRO holds 4 gallons vs 1.6 gallons — a 150% increase. Fine dust from sanders, CNC machines, and hardwood rip cuts fills the small chamber far faster than chips fill the main bin, making the G-800 PRO's larger box a meaningful operational upgrade.


The G-700 PRO ships in a cardboard carton. The G-800 PRO ships in a heavy-duty wooden crate due to its larger weight, size, and industrial-grade build.
Even though both models share the same core mechanical components, the G-800 PRO is engineered for higher performance through a 27% larger filter, a vertical adjustable intake, a 150% larger fine-dust box, a more spacious internal airflow path, a heavier and more robust structure, and top-mountable inlet options for modern ducting layouts. For shops that want maximum efficiency and the longest filter life, the G-800 PRO clearly stands out as the superior long-term investment. The G-700 PRO delivers the same proven Gyro Air technology in a more compact, accessible package.
