4.99.9% Empty Capsule Feeding Rate: Precise vacuum separation ensures minimal capsule waste.
Is the NJP-3800C the right filler for you?
✓ This is a fit if…
- You need around 228,000 capsules an hour as a sustained rate
- You're running product development, stability batches or small commercial runs
- You're filling powder, granule or pellets
- You run 00# to 5# capsules
- Your room holds 21 °C ± 3 °C and 40–60% humidity
✕ Look elsewhere if…
- You need more than 228,000 an hour → the NJP-5500C runs 330,000 for a modest step up
- This is your only machine and you plan to scale within a year → buying the 5500C now costs less than buying the 3800C twice
- You're doing bench-scale R&D only → a semi-automatic filler costs a fraction of this
- Your powder is very fine and highly potent → an enclosed rotary machine with dust extraction is not the same as a contained or isolator system. Tell us your OEB band first
- You need under 150,000 an hour → the NJP-2500C costs less and does the same job at that rate
- You need more than 228,000 → the NJP-5500C runs 330,000
Industrial-Scale Productivity: Delivers a stable, high-speed output to maximize the OEE of large-scale manufacturing facilities.
Patented High-Precision Yield: Maintains a 99.9% separation rate and consistent filling accuracy (±3.0%) for reliable batch quality.
Zero-Waste Material ROI: Integrated recovery system captures stray powder in a clean loop, significantly reducing high-value material loss.
Extreme Mechanical Durability: The heavy-duty frame and 100DS indexing box are designed for continuous operation without mechanical fatigue.
Advanced Cleanroom Integrity: The oil-free dry vacuum pump meets international (FTA) standards, preventing heat generation in GMP workshops.

The D suffix is a configuration, not just a speed step. C-type machines use a water-ring vacuum pump and external-groove cam lubrication. The D adds a dry vacuum pump — no water to refill, no scale build-up — plus enclosed internal-groove cams with automatic timed oiling, and a nano anti-corrosion coating over the same pharmaceutical-grade stainless steel. If your formulation is corrosive or your maintenance team is thin, that’s what you’re paying for.
Butterfly valve hopper with forced vibration
Replaces screw feeding with a vibration-equipped butterfly valve, forcing powders with poor liquidity (like TCM) to flow smoothly without clogging.
100DS indexing box
We use the 100DS cam indexing box with a 30mm output shaft, providing 30% more torque and stability than competitors using standard 83DS.
Negative-pressure powder recovery
Features a patented filling pedestal that instantly inhales powder from unseparated capsules into a reclaimer for ≥99.9% material recycling.
Guideway-driven capsule seeder
Utilizes a guideway transmission mechanism with an enclosed design to prevent dust and capsule fragments from interfering with orientation.
One-piece enclosed turntable
CNC-machined one-piece frame with dustproof skeleton seals, guaranteed for 3 years of maintenance-free operation.
Automatic timed lubrication
Integrated timing and quantitative oil supply system to maximize the service life of all moving transmission parts.
How Much API Are You Losing per Batch?
A sophisticated negative-pressure system recycles stray powder, delivering cost savings for high-volume runs.
Keeping Powder Out of the Drive System
The enclosed turntable runs three years without internal maintenance or manual oiling with a dual-lip skeleton dust ring to prevent powder ingress.
Running at 228,000/h Without Losing Fill Accuracy
Unlike smaller models, the NJP-3800C utilizes a 10-station workflow to ensure more precise capsule separation and locking at higher speeds.
Industrial Applications
Changeover: what you change and how long it takes
What you changed | What gets adjusted | Roughly how long |
Same capsule, different fill weight | Tamping pin depth on the dosing station | 15-30mins |
Fill weight beyond the adjustment range | Swap the dosing disc for a different thickness | 15-30mins |
Different capsule size | Full tooling set: upper and lower modules, tamping pins, capsule tubes, alignment combs, feeding combs, dosing disc, alignment bars | 15-30mins |
Dosing disc thickness is the second lever. When tamping depth reaches its mechanical limit and you still can’t hit your target fill weight, you change the disc rather than fighting the machine. It’s a physical volume change, not a calibration.
The gaps matter more than they sound. Dosing disc to copper ring: 0.08–0.12 mm. Isolation block to disc: 0.05–0.1 mm. Every disc change means resetting the second one. Too tight and the disc binds; too loose and powder leaks and your fill weight scatters.
Cleaning is the long part. Between products, the powder hopper, dosing ring, upper and lower modules, tamping pins and dosing disc all come out. Parts above the machine table are cleaned with alcohol on lint-free cloth — never gasoline, kerosene, hydrogen peroxide or acetone.
What to check before you order — from any supplier
Ask to see the machine running your powder, not a demo powder
Lactose and starch run beautifully on everything. Ask for a video of your own material, or send a 2 kg sample for a trial run. Any factory that won't do this is telling you something.
Ask what the sustained rate is, not the maximum rate
Catalogue output figures are peak numbers. Ask what the machine holds over an eight-hour shift with your fill weight and your capsule size, and what the reject rate looks like at that speed.
Ask for the operating manual before you pay
If the adjustment procedures aren't in it — tamping pin height, dosing disc clearances, vacuum settings — your operators will be calling the factory every time something drifts.
Ask which parts are wear parts and what they cost
On a capsule filler that means seals, tamping pins and the dosing disc. Get the list and the prices in writing with the quotation.
Ask what the electrical supply actually is
Most machines from Asia ship at 380V / 50Hz as standard. Confirm in writing that yours will arrive configured for your plant, and whether the output figure still holds after the change.
Ask who installs it and who trains your operators
"We provide installation support" can mean an engineer on your floor or a PDF. Ask which, ask for how many days, and ask what happens if commissioning takes longer.
Why Choose AIPAK
Why buy this machine from us
Accuracy you can check Fill weight accuracy is ±3% on pharmaceutical powder, ±4% on herbal powder. We run your material at factory acceptance testing and give you the actual figures for your formulation — not a number off a brochure.
The manual your operator can actually use An English operating and maintenance manual with the adjustment procedures in it — tamping pin height, dosing disc gaps, vacuum pressure. Ask to see it before you order.
Installation and training on site Our engineers install it, dial it in on your powder, and train your operators before they leave.
Factory-direct engineering You buy from the plant that builds the machine. Custom tooling, feeder configurations and change parts are a conversation with our engineers, not a request passed down a chain.
