Separate the manufacturing company from the model you are buying
Hangzhou ANEST IWATA Youjia
杭州阿耐思特岩田友佳空压机有限公司 is listed by the group as a compressor manufacturing and sales company in Qiantang, Hangzhou. It is distinct from the Shanghai industrial machinery company and Shanghai SCR.
The group dates the Hangzhou venture with Fair Friend to 2009 and describes twin-screw and claw development, machining and compressor-unit assembly there.
SLPJ · pressure and dryer suffixes matter
Compare the air you can use after the selected drying configuration
Single-head versus multiple-head
The Chinese catalogue separates 1.5–3.7 kW single-head packages from 7.5–30 kW multiple-head packages. Multiple heads are controlled according to demand; agree their operating sequence and usable output during maintenance.
Ask for a complete supply arrangement if interruption is unacceptable. Several heads in one enclosure do not by themselves establish independent standby capacity.
0.65–0.8 MPa control band
| SLPJ-37B Base configuration | 405 L/min |
|---|---|
| SLPJ-37B-01 Membrane dryer | 360 L/min |
0.8–1.0 MPa control band
| SLPJ-371B Base configuration | 345 L/min |
|---|---|
| SLPJ-371B-01 Membrane dryer | 300 L/min |
Keep the full suffix, pressure band and drying scope together. Obtain the current flow reference conditions and delivery guarantee before comparing quotations; the base machine's flow is not the dryer-equipped package's usable air.
SLPJ models and package selection →TFPJ · receiver-mounted oil-free air
A receiver absorbs a draw; it does not replace continuous capacity
Composite-resin piston route
The catalogue describes composite-resin pistons and oil-free compression. Compare the receiver arrangement, start/stop duty, ventilation and actual acoustic conditions with the enclosed scroll route.
| TFPJ37-10 | 3.7 kW 370 L/min |
|---|---|
| TFPJ55-10 | 5.5 kW 580 L/min |
Specify sustained demand and peak draw separately. Agree receiver volume/documentation, permitted operation and flow conditions; catalogue sound values are not a room-noise guarantee.
TFPJ configuration and installation brief →EFBS / CFBS · existing compressed-air inlet
Boost one consumer after measuring the inlet under load
Pressure increases locally
A booster takes an existing compressed-air supply and raises pressure for a particular consumer. Give the minimum inlet pressure while that consumer runs, required discharge pressure and demand cycle.
- Measure the available inlet during peak demand, including pipe losses.
- Obtain the named model's inlet limits and performance curve at those conditions.
- Agree receiver/control, upstream air treatment and handling of supply interruptions.
The China references list EFBS15-10: 1.5 kW, 0.8–1.0 MPa and CFBS75-20: 7.5 kW, 1.8–2.0 MPa. These are discharge control bands; use the exact variant's sheet for inlet and media approval.
Define clean air at the consumer, not just at the compressor
Moisture & particles
Oil-free compression is one part of the supply. For food-contact, instrument or laboratory air, specify the required dew point, filtration and sampling location. Agree the treatment and acceptance method for the actual process.
Evidence tied to the order
Request the offered model's test conditions, current documents and any applicable certificate's scope and validity. Group-level history or an oil-free product name is not an order-specific air-quality certificate.
Prepare the China supply and export scope together
- Model and usable duty
- Full SLPJ/TFPJ/booster suffix; air demand over time; pressure at the consumer; drying/filtration scope; actual flow basis. For a booster, add minimum dynamic inlet pressure and approved gas.
- Site and electrical version
- Voltage, frequency, phase, ambient conditions, ventilation and available space. Request dimensions, service access, drainage and receiver documentation for the destination.
- Production and support
- Actual manufacturing origin and supplier; current model sheet; applicable test records; maintenance parts and schedule; named commissioning/service responsibilities for this order.
Questions before selecting ANEST IWATA air equipment
Can I compare SLPJ-37B and SLPJ-37B-01 with the same air-delivery figure?
The Chinese sheet lists 405 L/min for the base model and 360 L/min for the membrane-dryer version at 0.65–0.8 MPa. Match the complete suffix and drying configuration and confirm the current guarantee.
Does a multiple-head scroll package give full output with one head stopped?
Obtain the actual head arrangement, operating sequence and remaining capacity. Determine whether a separate standby machine or receiver is needed for the consumer's allowable interruption.
Is the booster discharge band its inlet-pressure range?
No. Supply the minimum running inlet pressure and obtain the exact model's allowable inlet range and duty curve before sizing it.
Are all China catalogue models manufactured in Hangzhou?
Identify the origin and contracting supplier in the offer. The group confirms Hangzhou's compressor manufacturing role; its wider product catalogue spans multiple configurations and production sources.
