A model name and port size do not provide enough information to compare these two FRLs or judge a quotation. By checking the machine’s air demand, thread standard, pressure requirements, configuration and delivered cost, you can request the correct unit instead of paying for an unsuitable or incomplete assembly.
Key takeaways
- Request the exact variant, thread, gauge, drain and filtration rating.
- Choose AFC 2000 for 1/4-inch lines and BFC 4000 for 1/2-inch lines.
- Compare FRL with gauge price after adding GST, freight and fittings.
- Install the FRL in airflow direction and drain collected water regularly.
What should the Delhi quotation include for an AFC 2000 or BFC 4000?
There is no dependable single airtech afc 2000 bfc 4000 frl price in delhi until the seller confirms the exact variant. Gauge inclusion, drain construction, filtration rating, thread, GST and freight can change the delivered total; a low base price can exclude the gauge, delivery or tax.
1. Ask the seller to write the original Airtech or Airco marking, exact model suffix, port size and thread standard: BSP, BSPT or NPT. “1/4 inch” or “1/2 inch” alone is not enough.
2. Require separate line items for the FRL body, pressure gauge, fittings or adapters, GST, freight, delivery, installation and any warranty charge. This makes an frl with gauge price comparable with another offer.
3. Confirm whether the gauge is pre-fitted. Specify its scale, such as 0–10 bar or 0–16 bar; a 0–10 bar gauge gives clearer readings when your operating pressure is modest.
4. Before comparing offers, request the performance datasheet, batch number or manufacturing date, bowl material, drain type, filtration rating and replacement-part details. The datasheet should also identify rated flow, maximum working pressure and compatible replacement elements.
A quotation that says only “AFC 2000 FRL” or “BFC 4000 FRL” leaves you comparing labels rather than equivalent equipment. Ask for a GST-inclusive delivered total as well as the itemised price.
How do you choose between the 1/4-inch AFC 2000 and 1/2-inch BFC 4000?
Choose by usable flow and pressure drop, not port size alone. Ask the machine builder or maintenance team to record:
- Normal and peak air consumption
- Compressor or receiver pressure
- Required regulated pressure
- Simultaneous cylinder and valve operation
- Duty cycle
- Maximum acceptable pressure drop
| Option | Common format | Selection rule | Main risk |
|---|---|---|---|
| AFC 2000 | Smaller 1/4-inch format | Suits compact, lower-flow circuits when its rated flow meets peak demand | Restriction during simultaneous actuator movement |
| BFC 4000 | Larger 1/2-inch format | Suits higher-flow circuits only when its data confirms the required flow | Excess body size, clearance and cost on a low-flow machine |
A 1/4-inch or 1/2-inch label does not prove usable flow. Request rated flow at your inlet pressure and the manufacturer’s pressure-drop test conditions. A small FRL on a high-flow cylinder circuit can reduce downstream pressure and slow actuator movement.
Do not select the BFC 4000 merely because its port is larger. It offers no operating benefit on a compact, low-flow machine when its body needs more space and costs more.
Before ordering an airtech afc 2000 frl, inspect the machine port, inlet and outlet orientation, bowl clearance and actual thread. Confirm whether it is BSP, BSPT or NPT; never force BSP into NPT. If you use an adapter, check its passage size and every added leak point before installation.
What must you confirm about the filter, regulator, lubricator and gauge?
The filter removes liquid condensate and solid particles at its stated micron rating; it does not replace a dryer for water vapour or a coalescing filter for compressor-oil aerosol. The regulator controls downstream pressure, so its range, maximum inlet pressure and gauge scale must match the machine.
| Component | Confirm in the quotation | Why it matters |
|---|---|---|
| Filter | Micron rating, rated flow, bowl capacity, bowl material, drain type and replacement element | A saturated element restricts air; a particulate filter cannot remove fine oil mist or vapour |
| Regulator | Regulated pressure range, maximum inlet pressure, rated flow and pressure-drop test conditions | An undersized unit lowers pressure when cylinders and valves operate together |
| Lubricator | Included or omitted, approved oil type and equipment-maker drip-rate setting | Omit it for oil-free cylinders, instrumentation, painting, food-related equipment and components specified for oil-free air |
| Gauge | Included, scale such as 0–10 bar or 0–16 bar, connection and accuracy | The gauge must show regulated downstream pressure, not supply pressure |
Confirm whether the quoted AFC 2000 or BFC 4000 actually includes a lubricator; the model name alone does not prove the configuration. Excess oil wets silencers, fouls solenoid valves and causes erratic operation.
Request these matching figures for both quotations:
- Operating-temperature range
- Maximum working pressure
- Rated flow and test pressure
- Compatible bowl, drain, filter element, gauge and lubricator replacements
Read and set the gauge while air flows at the machine’s normal demand, not during a static, no-load check. That reading exposes pressure drop that a resting gauge hides.
How should you install and maintain the selected FRL?
An FRL installed backwards, with an inverted bowl or no drainage clearance, can restrict airflow and turn routine servicing into a shutdown.
1. Mount the assembly close to the pneumatic machine, with the filter first, regulator next and lubricator last. Follow the airflow arrow on the body, keep the bowl upright, leave clear space beneath it and install an upstream shut-off valve.
2. Before opening the bowl, element housing or drain, isolate the air supply, lock out the shut-off valve where required and bleed residual pressure through a safe vent point. Never service a pressurised bowl.
3. Match the port threads before installation. Do not force BSP and NPT together, and keep thread sealant out of the air passage and regulator mechanism; excess sealant can obstruct valves and cause erratic regulation.
4. Drain condensate according to the fitted design. A manual drain needs an operator, while semi-automatic and automatic drains add failure points when compressor oil, rust or pipe scale contaminates the mechanism.
5. Set service intervals from condensate load and pressure-drop readings, not a calendar alone. Inspect the bowl and drain routinely; replace a saturated or damaged element, and replace any leaking gauge, seal, bowl or drain.
An integrated FRL saves footprint and connection points. Separate modules make individual replacement and future filtration changes easier, but require more space, joints and leak checks.
How can you buy the correct unit from an Airtech FRL dealer in Delhi?
Turn the purchase into a written checklist before contacting an airtech frl dealer in delhi. Send a photograph of the existing assembly and nameplate, then provide:
1. Machine port thread and standard, normal and peak flow, inlet and regulated pressure, air-quality requirement, ambient temperature, preferred drain, gauge range and available installation space.
2. Confirmation of the exact model marking and Airtech/Airco identity; filtration rating; bowl capacity and material; maximum working pressure; operating-temperature range; rated flow and test conditions; seal material; lubricator inclusion; and gauge connection. Ask whether replacement bowls, elements, gauges, drains and lubricators are available.
3. Stock status, manufacturing batch or date, dispatch lead time, Delhi pickup or delivery options, GST-inclusive delivered pricing, warranty, return terms and technical support. Require separate prices for fittings, adapters and installation if they are not included.
Multitech Pneumatics And Hydraulics can verify the quoted variant against your application and help match the thread, gauge, drain and replacement parts. Obtain every detail in writing before payment, because visually similar FRLs can carry the same apparent size marking while differing in thread, bowl construction or pressure range.
A performance datasheet is the best comparison document; without it, two “AFC 2000” or “BFC 4000” quotations are not technically equivalent.
