Nais inverters are legacy variable frequency drives produced by Matsushita Electric Works under the Nais brand – the industrial automation product line that preceded the 2008 corporate consolidation of all Matsushita group entities into Panasonic. Malaysian manufacturers encountering Nais VF0, VF-6E, VF-7F, VF-8X, and VF-CE inverters on older installed equipment should direct replacement sourcing and new installation specifications to current Panasonic Compact AC Drives, which continue the engineering lineage of the Nais VF-series under active production.
Flextech Industrial Supplies stocks current Panasonic Compact AC Drives (VF200 and MK300 series) as the in-production successors to Nais VF-series inverters. For Malaysian buyers seeking direct Nais model replacement from remaining distributor stock, Flextech provides sourcing assistance on a best-effort basis. This page provides accurate brand transition history to help Malaysian maintenance engineers and procurement teams navigate Nais-branded equipment on existing installations.

The Nais Brand: Corporate History and Transition
Nais was the industrial automation product brand of Matsushita Electric Works Ltd., the industrial and housing products division of the Matsushita Electric Industrial group - the Japanese conglomerate that now operates as Panasonic Corporation globally.
The corporate lineage: Matsushita Electric Works → renamed Panasonic Electric Works in 2004 → fully merged into Panasonic Corporation in 2011 following the 2008 announcement. The Nais brand designation for industrial automation products (PLCs, inverters, relays, sensors) was retired progressively between 2004 and 2011 as Panasonic branding replaced it across all Matsushita industrial products.
Malaysian industrial plants installed Nais-branded inverters primarily between 1990 and 2010 - a 20-year period during which Nais was the standard brand designation for Matsushita Electric Works automation products in Southeast Asia. Malaysian palm oil mills, rubber glove manufacturing plants, and F&B processing facilities installed significant quantities of Nais VF0, VF-7F, and VF-8X inverters on pump, fan, and conveyor drives during this period.
Nais VF-Series: Model Reference and Current Equivalents
| Nais Model | Power Range | Current Panasonic Equivalent | Status |
| VF0 (BFV00xxx) | 0.2-2.2 kW | VF200 | Out of production |
| VF-6E (BFV60xxx) | 0.75-7.5 kW | VF200 | Out of production |
| VF-7F (BFV70xxx) | 0.75-22 kW | MK300 | Out of production |
| VF-8X (BFV80xxx) | 2.2-75 kW | MK300 | Out of production |
| VF-CE (BFVCExxx) | 3.7-45 kW | MK300 | Out of production |
Nais VF0 series (model prefix BFV00) covered 0.2-2.2 kW - the compact Nais inverter for small-motor speed control in Malaysian packaging, conveyor, and auxiliary equipment drives. VF0 was the highest-volume Nais inverter in Malaysian distribution. Current equivalent: Panasonic VF200 compact general-purpose inverter.
Nais VF-7F series (model prefix BFV70) covered 0.75-22 kW - the mid-range Nais inverter for general-purpose pump, fan, and conveyor drives in Malaysian manufacturing. VF-7F was the workhorse Nais inverter installed in Malaysian F&B, rubber processing, and general manufacturing. Current equivalent: Panasonic MK300 high-performance compact inverter.
Nais VF-8X series (model prefix BFV80) covered 2.2-75 kW - the higher-power Nais inverter for heavy-duty Malaysian industrial applications including palm oil screw press drives, large fan drives, and material handling conveyor motors. Current equivalent: Panasonic MK300 at overlapping power ranges.
Current Panasonic Equivalents: What to Specify Now
Malaysian buyers specifying replacement for Nais VF-series inverters should contact Flextech for current [Panasonic Compact AC Drives Malaysia](/product-category/compact-ac-drives-panasonic/) - the VF200 and MK300 series that directly continue the Nais engineering lineage under Panasonic branding.
For Nais VF0 replacement: Specify Panasonic VF200 at the same kW rating. VF200 provides equivalent V/f control capability with updated parameter structure, current Malaysian compliance documentation (CE, RoHS), and active Panasonic warranty support.
For Nais VF-7F and VF-8X replacement: Specify Panasonic MK300 at the same kW rating. MK300 provides sensorless vector control (an improvement over VF-7F's V/f-only control), Modbus RTU communication, built-in PID, and active Panasonic warranty support. Parameter migration assistance is available from Flextech on common VF-7F → MK300 retrofits in Malaysian palm oil and rubber plant applications.
Malaysian maintenance engineers replacing Nais inverters should note: terminal assignments and parameter numbering differ between Nais VF-series and current Panasonic VF200/MK300. Direct parameter copy is not possible - a commissioning session is required for each replacement installation.
Why Nais Inverters Still Appear in Malaysia
Nais-branded inverters continue operating on Malaysian manufacturing equipment installed before 2010 for two reasons: inverter design life of 10-15 years (capacitor service life dependent), and the high capital cost of equipment replacement on functional machinery. A Nais VF-7F installed in 2005 on a Malaysian palm oil mill pump drive reached its statistical replacement window circa 2015-2020, but many continue operating on PM-maintained machinery in 2026.
For Malaysian plant maintenance engineers, the practical implication: when a Nais VF-7F fails in 2026, the replacement path is Panasonic MK300 (not a Nais unit from secondary market), because:
- Remaining Nais VF-7F stock from secondary distributors carries unknown service history and capacitor age
- Grey-market Nais inverters lack valid warranty and documentation for CE-conforming machine records
- Current Panasonic MK300 provides improved control performance (sensorless vector vs VF-7F's V/f) at comparable Malaysian distributor pricing
Genuine OEM vs Grey-Market Nais Inverters
Grey-market Nais inverter stock - refurbished, repaired, or parallel-import units - circulates in Malaysia via repair shops and online platforms. Flextech does not source from grey-market Nais inventory. For Nais model-specific replacement, Flextech provides genuine remaining distributor stock where available, or presents current Panasonic Compact AC Drives as the authorised successor path.
How to Order
Malaysian buyers with Nais inverter replacement requirements should contact Flextech with the Nais model number (from the unit nameplate, e.g., "BFV70222FBP" for a VF-7F 2.2 kW 3-phase unit). Flextech will:
- Check stock for direct Nais model match (where available)
- Present current Panasonic Compact AC Drives equivalent with pricing
- Provide parameter cross-reference guidance for VF-7F → MK300 commissioning
Flextech provides Nais replacement quotations within 24-48 hours. Same-day Klang Valley dispatch on Panasonic VF200 and MK300 standard ratings.

Nais Inverter FAQ
What is a Nais inverter and who makes it?
Nais is the legacy industrial brand of Matsushita Electric Works, now Panasonic Industry. Nais VF-series inverters (VF0, VF-7F, VF-8X) are out of primary production. Current equivalent: Panasonic Compact AC Drives (VF200, MK300).
Can Flextech supply Nais VF0 or VF-7F inverters in Malaysia?
Best-effort basis from remaining stock. Flextech recommends current Panasonic VF200 (Nais VF0 equivalent) and MK300 (Nais VF-7F equivalent) - active production with full warranty.
What is the current replacement for Nais VF-series inverters?
Panasonic VF200 replaces Nais VF0/VF-6E. Panasonic MK300 replaces Nais VF-7F/VF-8X/VF-CE. Both are stocked by Flextech with same-day Klang Valley dispatch on standard ratings.
Are Nais inverters the same as Panasonic inverters?
Yes. Nais was the former Matsushita Electric Works industrial brand - Panasonic is the current brand after the 2008 group consolidation. Same engineering organisation, same production facilities.
Where can I get Nais inverter replacement in Malaysia?
Contact Flextech Industrial Supplies, Puchong, Selangor. Provide the Nais model number from the unit nameplate. Flextech provides direct Nais sourcing where available, plus Panasonic Compact AC Drives replacement options with parameter cross-reference guidance.
