Outer and inner filters
The removable electrostatic outer stage catches coarser dust, while the inner three-pocket stage addresses finer airborne dust. Their airflow order matters.

An original educational poster identifies 10 documented construction features. The numbered descriptions remain readable below the artwork on narrow screens.
- Outer electrostatic filter
First removable intake stage captures larger airborne dust.
- Inner three-pocket filter
Second removable stage traps finer particles.
- Filter clips
Retain the outer intake frame for tool-free filter access.
- Sheet-metal air box
Supports the filter opening, blower and controls.
- Squirrel-cage fan wheel
Moves filtered air through the blower passage.
- Fan housing
Encloses and directs air leaving the wheel.
- Motor and support
Drives the wheel; remains a model-specific service group.
- Control plate
Groups speed, timer and power controls at the rear.
- Mounting eyes and brackets
Suspend the heavy unit only from structural support.
- Remote control
Starts and selects documented speed and timer settings.

Air enters through the outer filter and inner three-pocket filter before the blower returns it to the room. The model-specific service breakdown separates the motor and support, fan housing, and fan wheel along one axle; the illustration shows those relationships without exposing circuit-board internals. Original educational artwork depicts documented component groups and their relationships; it is not a service sequence or a replacement for the exact model manual.
02 / Understand the tool
What it is and what each part does
The U.S. JET AFS-1000B, stock 708620B, is a 115-volt ambient air filtration unit. Its manufacturer manual lists a 5-micron outer electrostatic filter, 1-micron inner three-pocket filter and three airflow settings: 556, 702 and 1044 CFM. A separate motor-driven blower returns filtered air to the room. The original TWG image depicts the B model's low rectangular sheet-metal housing and filter opening without manufacturer branding. It does not mix in the later AFS-1000C display module or an international 230-volt variant.
Room air enters the clipped outer filter, crosses the inner pocket filter and then reaches a motor-driven fan wheel inside a round housing. The blower sends air back into the workshop through the opposite end. A control plate and remote select speed and timed operation. The service drawing supports distinct filter, air-box, fan wheel, fan housing, motor and control-plate groups; the study keeps electronics enclosed rather than claiming a precise hidden wiring assembly. This is a component relationship study, not a field-repair sequence.
Air box and filter clips
The metal enclosure supports both stages; clips retain the outer filter and permit access only after unplugging the unit.
Fan, housing and motor
The maker lists fan blade OO1055, housing OO1056 and motor OO1057 separately. Service is for qualified personnel, not routine filter maintenance.
Controls and remote
The rear control plate, three speeds and 2/4/8-hour timer are documented for this B model; the small remote is an accessory.
Structural suspension
Four approved eye bolts or brackets attach to a support capable of at least the manual's 100-pound requirement, never just drywall or a drop-ceiling grid.

Set, guide and control the action
These decisions make the mechanism useful at the bench.
Locate and mount
Choose an unobstructed location and anchor every mounting point into building structure according to the manufacturer.
Seat both filters
Insert the inner pocket filter, then the outer stage in the marked airflow direction and engage the clips.
Choose speed and time
Select low, medium or high airflow; use the remote's 2, 4 or 8 hour timer only as directed.
Dusty machine session
Use source extraction at a saw, planer or sander first; run the ambient unit to reduce dust left suspended in the room.
Post-work air cycle
Use a documented timer interval after work while continuing to observe the manufacturer's electrical and unattended-use precautions.
Filter service
Unplug the unit, release the clips and inspect both filter stages without disturbing the internal electrical compartment.
03 / At the bench
Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Read the U.S. stock 708620B manual; confirm local supply is grounded 115 V / 60 Hz.
- Plan an unobstructed intake and outlet path and verify overhead structure supports at least the manual's 100-pound load.
- Install four eye bolts or brackets with the supplied fasteners according to the JET mounting instructions.
- With power disconnected, seat the inner three-pocket filter and the outer electrostatic filter in their indicated airflow direction.
- Run source dust capture at the tool; then operate the ambient unit at a suitable speed and timer setting.
- Inspect airflow and filter loading regularly; clogged filters reduce circulation.
- Unplug and wait for the fan to stop before releasing clips, cleaning or replacing filters.
Ambient filtration is supplementary
This unit recirculates room air after dust is airborne. It does not replace capture at the cutter or respiratory protection suited to the task.
Model suffix matters
B-model parts and its 115-volt motor cannot be assumed to match the C series or 230-volt international machines.
Filter rating and real exposure differ
The manual's micron labels and airflow figures describe the machine, not a guarantee that a particular workshop meets an exposure limit.
What changes by model or material
JET identifies 708731 as its electrostatic outer stage.
The manual lists 708732 as a washable alternative; use only a compatible JET replacement and follow its care directions.
JET lists 708734 as an option, but the ordinary two-stage wood-dust study does not claim a charcoal stage is included.
Choosing the tool
- Calculate room volume and consider the manufacturer's 556/702/1044 CFM settings without assuming all air is uniformly mixed.
- Confirm overhead structure, electrical supply and clear filter-access space before purchase.
- Budget for genuine compatible outer and inner filters, and retain source extraction at each machine.
Useful accessories
- Supplied remote control
- Four structural mounting eyes or brackets
- Compatible replacement filter set
Consumables
- JET 708731 outer filter or supported 708732 option
- JET 708733 inner three-pocket filter
04 / Keep control
Care, troubleshooting and safety
Stop the tool and disconnect power before investigating a fault or changing a part.
Care checklist
- Unplug before opening the intake and allow the fan to stop.
- Inspect clips and replace or clean filters on the maker's schedule and as loading demands.
- Keep intake and outlet clear; check that the unit remains securely suspended.
- Do not open the control or motor compartment for ordinary maintenance.
Common mistakes
- Using an AFS-1000C or international-voltage parts diagram for this B model.
- Mounting into drywall or a suspended ceiling grid.
- Running with an omitted or reversed filter stage.
- Expecting ambient filtration to capture dust at its source.
Safety at the operation
- Follow the grounding and 115-volt instructions for the U.S. unit.
- Mount only to structural support rated for at least 100 pounds as the manual states.
- Do not use the unit for volatile fumes, smoke or materials beyond its wood-dust purpose.
- Unplug before filter access; do not service internal electrical parts unless qualified.
When the result goes wrong
Check outer and inner filters, blocked grille, fan operation and the selected speed.
Check remote batteries, line of sight and the manual control before suspecting internal electronics.
Turn off and unplug; inspect airflow restrictions and follow the manual's reset interval rather than bypassing the switch.
